    United States Court of Appeals
    For the Seventh Circuit
    No. 97-3253
    Dr. Iris I. Varner, et al.,
    Plaintiffs-Appellees,
    and
    United States of America,
    Intervening Appellee,
    v.
    Illinois State University, et al.,
    Defendants-Appellants.
    Appeal from the United States District Court
    for the Central District of Illinois, Peoria Division.
    No. 95 C 1355--Michael M. Mihm, Judge.
    On Remand from the United States Supreme Court
    No. 98-1117
    Argued May 31, 2000--Decided September 6, 2000
    Before Flaum, Chief Judge, and Bauer and
    Harlington Wood, Jr., Circuit Judges.
    Flaum, Chief Judge. The plaintiffs comprise a
    class of tenured and tenure-track female faculty
    members at Illinois State University (the
    "University") who contend that the University
    pays female professors less money than their male
    counterparts. In 1995, the plaintiffs filed suit
    seeking both monetary and injunctive relief
    against the University and various of its
    officers and agents (collectively the
    "defendants"), alleging violations of the Equal
    Pay Act, 29 U.S.C. sec. 206(d), and Title VII, 42
    U.S.C. sec. 2000e et seq. The University, which
    the plaintiffs concede is a state entity, moved
    to dismiss the Equal Pay Act claim, as well as
    the claim for compensatory relief under Title
    VII, arguing that the Eleventh Amendment bars
    federal jurisdiction over these claims. The
    district court denied the defendants’ Eleventh
    Amendment defense, and the defendants appealed
    that decision to this Court under the collateral
    order doctrine, see Puerto Rico Aqueduct & Sewer
    Auth. v. Metcalf & Eddy, Inc., 
    506 U.S. 139
    , 145
    (1993) (holding that the collateral order
    doctrine allows for immediate appellate review of
    the denial of an Eleventh Amendment immunity
    claim).
    In our initial consideration of this case, we
    affirmed the district court in all respects,
    finding that Congress clearly intended to
    abrogate the States’ Eleventh Amendment immunity
    through its passage of the Equal Pay Act, and
    that this abrogation was a valid exercise of
    congressional authority under sec. 5 of the
    Fourteenth Amendment. See Varner v. Illinois St.
    Univ., 
    150 F.3d 706
    , 717 (7th Cir. 1998),
    vacated, 
    120 S. Ct. 928
    (2000). Although we
    further determined that Title VII contained an
    explicit abrogation of the States’ Eleventh
    Amendment immunity, we did not consider whether
    that abrogation was a valid exercise of
    congressional authority because we held that the
    defendants had waived that issue by failing to
    present it sufficiently to the district court.
    See 
    id. at 717
    n.14. The defendants appealed our
    rejection of their Eleventh Amendment defense to
    the United States Supreme Court.
    On writ of certiorari to the Supreme Court, our
    original opinion affirming the district court was
    vacated and remanded, see Illinois St. Univ. v.
    Varner, 
    120 S. Ct. 928
    (2000), for further
    consideration in light of the Court’s intervening
    decision in Kimel v. Florida Bd. of Regents, 
    120 S. Ct. 631
    (2000) (holding that the Age
    Discrimination in Employment Act ("ADEA"), 29
    U.S.C. sec. 621 et seq., was not a valid
    abrogation of the States’ sovereign immunity).
    After considering the defendants’ assertion of
    Eleventh Amendment immunity against the backdrop
    of the Supreme Court’s decision in Kimel, it
    remains our conclusion that the district court
    properly rejected the defendants’ claim of
    sovereign immunity and denied their motion to
    dismiss. Consequently, we affirm the decision of
    the district court.
    I.  Analysis
    The Eleventh Amendment provides that, "The
    Judicial power of the United States shall not be
    construed to extend to any suit in law or equity,
    commenced or prosecuted against one of the United
    States by Citizens of another State, or by
    Citizens of Subjects of any Foreign State." U.S.
    Const. amend. XI. While the Eleventh Amendment
    appears to restrict only the federal courts’
    Article III diversity jurisdiction, the Amendment
    has long been understood "to stand not so much
    for what it says, but for the presupposition of
    our constitutional structure which it confirms."
    Blatchford v. Native Village of Noatak, 
    501 U.S. 775
    , 779 (1991). Under the Eleventh Amendment,
    each State in our federal system remains a
    sovereign entity and may not be sued by an
    individual without its consent, see Seminole
    Tribe of Florida v. Florida, 
    517 U.S. 44
    , 54
    (1996) (citing Hans v. Louisiana, 
    134 U.S. 1
    , 13
    (1890)).
    Although the Eleventh Amendment grants
    unconsenting States immunity from suit in federal
    court, that immunity is not absolute. See College
    Savings Bank v. Florida Prepaid Postsecondary
    Educ. Expense Bd., 
    119 S. Ct. 2219
    , 2223 (1999);
    see also Fitzpatrick v. Bitzer, 
    427 U.S. 445
    , 456
    (1976) ("[T]he Eleventh Amendment, and the
    principles of state sovereignty which it
    embodies, . . . are necessarily limited by the
    enforcement provisions of sec. 5 of the
    Fourteenth Amendment."). Congress may
    constitutionally abrogate the States’ Eleventh
    Amendment immunity if two criteria are satisfied:
    (1) Congress must unequivocally express its
    intent to abrogate the States’ sovereign
    immunity; and (2) in abrogating that immunity,
    Congress must act pursuant to a valid exercise of
    power. See Seminole 
    Tribe, 517 U.S. at 55
    .
    Because the defendants no longer contest
    Congress’ intent to abrogate the States’ Eleventh
    Amendment immunity in this case, we need only
    consider the question of whether the abrogations
    of sovereign immunity contained in the statutes
    at issue are valid exercises of congressional
    power under sec. 5 of the Fourteenth
    Amendment./1
    In City of Boerne v. Flores, 
    521 U.S. 507
    (1997), the Supreme Court explained that
    "[l]egislation which deters or remedies
    constitutional violations can fall within the
    sweep of Congress’ enforcement power even if in
    the process it prohibits conduct which is not
    itself unconstitutional." 
    Id. at 518;
    see also
    
    Kimel, 120 S. Ct. at 644
    ("Congress’ power ’to
    enforce’ the [Fourteenth] Amendment includes the
    authority both to remedy and to deter violation
    of rights guaranteed thereunder by prohibiting a
    somewhat broader swath of conduct, including that
    which is not itself forbidden by the Amendment’s
    text."). At the same time, the City of Boerne
    decision made clear that this affirmative grant
    of congressional power is limited to "enforcing"
    the Amendment’s restrictions on the States and
    does not extend to determining what constitutes
    a constitutional violation. City of 
    Boerne, 521 U.S. at 519
    . Recognizing that Congress must have
    latitude in determining where the line lies
    between appropriate remedial legislation and a
    substantive redefinition of a constitutional
    right, the Court held that "[t]here must be a
    congruence and proportionality between the injury
    to be prevented or remedied and the means adopted
    to that end." 
    Id. at 520.
    Because the requirements of congruence and
    proportionality mark the boundaries of Congress’
    Fourteenth Amendment enforcement power, and
    because Congress lacks the power to abrogate the
    States’ sovereign immunity under Article I of the
    Constitution,/2 see Seminole 
    Tribe, 517 U.S. at 72-73
    , congressional legislation that creates a
    cause of action against the States must satisfy
    the congruence and proportionality test. In
    Kimel, 
    120 S. Ct. 631
    , the Supreme Court used the
    congruence and proportionality test to determine
    whether the ADEA validly abrogated the States’
    sovereign immunity. The ADEA makes it unlawful
    for an employer, including a State, "to fail or
    refuse to hire or to discharge any individual or
    otherwise discriminate against any individual .
    . . because of such individual’s age," 29 U.S.C.
    sec. 623(a)(1). The Kimel Court held that,
    although the ADEA contained a clear statement of
    Congress’ intent to abrogate the States’ Eleventh
    Amendment immunity, that abrogation exceeded
    Congress’ Fourteenth Amendment enforcement power.
    
    Kimel, 120 S. Ct. at 640-50
    .
    Applying the congruence and proportionality
    test, the Kimel Court relied on a number of
    factors in concluding that Congress exceeded its
    authority in creating an individual cause of
    action for money damages against the States under
    the ADEA. Because age is not a suspect
    classification under the Equal Protection Clause,
    States may discriminate on the basis of age
    without offending the Fourteenth Amendment if the
    challenged age classification is rationally
    related to a legitimate state interest. The Court
    found that the ADEA, "through its broad
    restriction on the use of age as a discriminating
    factor, prohibits substantially more state
    employment decisions and practices than would
    likely be held unconstitutional under the
    applicable [constitutional] standard." 
    Id. at 647.
    Furthermore, the Court found little in the
    ADEA’s legislative record to confirm that age
    discrimination by the States was a widespread
    problem that demanded a strong remedy. See 
    id. at 648-49.
    "In light of the indiscriminate scope of
    the Act’s substantive requirements, and the lack
    of evidence of widespread and unconstitutional
    age discrimination by the States," the Court held
    that the ADEA’s abrogation of the States’
    Eleventh Amendment immunity was not a valid
    exercise of Congress’ enforcement power under
    sec. 5 of the Fourteenth Amendment. 
    Id. at 650.
    This Court has recently applied the congruence
    and proportionality test in the context of
    individual suits against the States under the
    Americans With Disabilities Act ("ADA"), 42
    U.S.C. sec. 12111 et seq. In Erickson v. Board of
    Governors of State Colleges and Universities for
    Northeastern Ill. Univ., 
    207 F.3d 945
    (7th Cir.
    2000), we held that Title I of the ADA, 42 U.S.C.
    sec.sec. 12111-12117, which prohibits
    discrimination in employment based on disability
    and requires employers to reasonably accommodate
    disabled individuals, was an invalid exercise of
    congressional authority under sec. 5 of the
    Fourteenth Amendment. See also Stevens v.
    Illinois Dep’t of Transp., 
    210 F.3d 732
    (7th Cir.
    2000). In reaching this conclusion, we determined
    that "the disparate-impact and mandatory-
    accommodation rules found in the ADA" far
    exceeded the constitutional protections provided
    by the Equal Protection Clause. 
    Erickson, 207 F.3d at 951
    ; see also 
    Stevens, 210 F.3d at 738
    .
    Furthermore, we concluded that these provisions
    could not be sustained as "reasonable
    prophylactic legislation." 
    Erickson, 207 F.3d at 951
    -52; see also 
    Stevens, 210 F.3d at 740-41
    .
    Underlying this holding was our understanding
    that Congress could not subject disability
    discrimination, which receives only rational
    basis review under the Constitution, see Cleburne
    v. Cleburne Living Center, 
    473 U.S. 432
    , 442-46
    (1985), to more searching scrutiny. See 
    Erickson, 207 F.3d at 951
    (holding that the ADA "exceed[s]
    the sec. 5 power . . . at least to the extent it
    extends beyond remedies for irrational
    discrimination"). In light of these principles
    drawn from prior precedent, we now review the
    defendants’ challenge to the validity of
    Congress’ abrogation of the States’ Eleventh
    Amendment immunity in the Equal Pay Act de novo,
    see EEOC v. AIC Sec. Investigations, Ltd., 
    55 F.3d 1276
    , 1279 (7th Cir. 1995) (stating that
    pure claims of law are reviewed de novo).
    A.   The Equal Pay Act
    The Equal Pay Act prohibits discrimination in
    wages based on gender./3 In order to prevail on
    an Equal Pay Act claim, an employee must first
    demonstrate unequal pay for "equal work on jobs
    the performance of which requires equal skill,
    effort, and responsibility, and which are
    performed under similar working conditions." 29
    U.S.C. sec. 206(d)(1); see Corning Glass Works v.
    Brennan, 
    417 U.S. 188
    , 195 (1974). Once an
    employee has met her burden of showing unequal
    pay for equal work, an employer may avoid
    liability under the Act by proving that the wage
    disparity exists "pursuant to (i) a seniority
    system; (ii) a merit system; (iii) a system which
    measures earnings by quantity or quality of
    production; or (iv) a differential based on any
    other factor other than sex." 29 U.S.C. sec. 206
    (d)(1); see Corning 
    Glass, 417 U.S. at 196
    . In
    effect, the provisions of the Equal Pay Act
    establish a rebuttable presumption of sex
    discrimination such that once an employee has
    demonstrated that an employer pays members of one
    sex more than members of the opposite sex, the
    burden shifts to the employer to offer a gender-
    neutral justification for that wage differential.
    See 
    id. at 196;
    Fallon v. Illinois, 
    882 F.2d 1206
    , 1211 (7th Cir. 1989).
    Because a prima facie case under the Equal Pay
    Act requires only an initial showing of a wage
    differential between the sexes, the Act’s
    remedial provisions do not perfectly mirror the
    Constitution’s prohibition on gender
    discrimination. Under the Equal Pay Act, an
    employer is potentially subject to liability
    without a showing of discriminatory intent. See
    Stopka v. Alliance of Am. Insurers, 
    141 F.3d 681
    ,
    685 (7th Cir. 1998) ("The E[qual] P[ay] A[ct]
    does not require proof of discriminatory
    intent."); see also Berry v. Board of Supervisors
    of LSU, 
    715 F.2d 971
    , 975 (5th Cir. 1983)
    (holding that the mere allegation that a female
    professor was paid less than a male colleague for
    equal work stated a claim under the Equal Pay
    Act). In contrast, in order to make out a claim
    of gender discrimination under the Constitution,
    an individual must demonstrate an intent to
    discriminate on the part of the employer. See
    Personnel Administrator of Mass. v. Feeney, 
    442 U.S. 256
    , 274 (1979) (stating that it is
    "purposeful [gender] discrimination . . . that
    offends the Constitution") (internal quotation
    omitted); Washington v. Davis, 
    426 U.S. 229
    , 238-
    39 (1976). Because the Equal Pay Act allows a
    finding of gender discrimination absent a showing
    of discriminatory intent, while the Constitution
    does not, the effect of the Equal Pay Act’s
    burden-shifting remedial scheme is to prohibit at
    least some conduct that is constitutional.
    The plaintiffs concede that the Equal Pay Act
    does not preclude the possibility that an
    employer will be held liable for conduct that is
    not prohibited by the Constitution. However, as
    the plaintiffs note, the Supreme Court has made
    clear that the mere fact that a statute’s
    remedial regime is broader in scope than the
    constitutional prohibitions against
    discrimination does not mean that the statute is
    not a proportional and congruent response to that
    problem. See 
    Kimel, 120 S. Ct. at 644
    ("Congress’
    sec. 5 power is not confined to the enactment of
    legislation that merely parrots the precise
    wording of the Fourteenth Amendment."); City of
    
    Boerne, 521 U.S. at 518
    . Section 5 of the
    Fourteenth Amendment is a remedial provision, and
    Congress has both the power and the discretion to
    enforce its guarantees through prohibitions
    broader than those contained in the Constitution.
    See 
    Kimel, 120 S. Ct. at 644
    . Furthermore, because
    "the line between measures that remedy or prevent
    unconstitutional actions and measures that make
    a substantive change in the governing law is not
    easy to discern, . . . Congress must have wide
    latitude in determining where it lies." City of
    
    Boerne, 521 U.S. at 519
    -20; see also 
    Kimel, 120 S. Ct. at 644
    ("[T]he determination whether
    purportedly prophylactic legislation constitutes
    appropriate remedial legislation, or instead
    effects a substantive redefinition of the
    Fourteenth Amendment right at issue, is often
    difficult."); Katzenbach v. Morgan, 
    384 U.S. 641
    ,
    651 (1966) ("Correctly viewed, sec. 5 is a
    positive grant of legislative power authorizing
    Congress to exercise its discretion in
    determining whether and what legislation is
    needed to secure the guarantees of the Fourteenth
    Amendment."). The question before us, therefore,
    is not whether the remedial provisions of the
    Equal Pay Act prohibit some constitutional
    conduct. Instead, we must consider whether the
    Act can be characterized as a proportional and
    congruent response to the problem of
    unconstitutional wage discrimination based on
    gender.
    The defendants contend that the burden-shifting
    effect of the Equal Pay Act renders it an invalid
    exercise of congressional authority under sec. 5
    of the Fourteenth Amendment because, like the
    ADEA, it is "so out of proportion to a supposed
    remedial or preventive object that it cannot be
    understood as responsive to, or designed to
    prevent, unconstitutional behavior." City of
    
    Boerne, 521 U.S. at 532
    . However, unlike the
    ADEA, which "impose[d] substantially higher
    burdens on state employers" than the
    Constitution, 
    Kimel, 120 S. Ct. at 648
    , the
    remedial regime of the Equal Pay Act is less
    indiscriminate in scope than the ADEA. In passing
    the Equal Pay Act, Congress did not prohibit all
    wage practices that result in a disparate impact
    upon the sexes, nor did it provide for liability
    upon a mere showing of unequal pay. See EEOC v.
    Francis W. Parker Sch., 
    41 F.3d 1073
    , 1077 (7th
    Cir. 1994) (stating that the Equal Pay Act "has
    been construed to preclude disparate impact
    claims") (citing County of Wash. v. Gunther, 
    452 U.S. 161
    , 170-71 (1981)); see also Marshall v.
    City of Sheboygan, 
    577 F.2d 1
    , 4 (7th Cir. 1978)
    (stating that Congress’ purpose in enacting the
    Equal Pay Act was not to prohibit all disparities
    in pay between men and women, but rather to
    "eliminate ’discrimination on account of sex in
    the payment of wages.’") (quoting Preamble, Equal
    Pay Act, Pub. L. No. 88-38, 77 Stat. 56). Rather,
    an examination of the purpose of the Equal Pay
    Act, and an evaluation of its remedial scheme,
    demonstrate that the Act is targeted at the same
    kind of discrimination forbidden by the
    Constitution.
    In comparing the provisions of the ADEA
    disapproved in Kimel, and the remedial scheme of
    the Equal Pay Act, perhaps the most significant
    difference between the two statutes is in the
    exemptions from liability provided to employers
    once a prima facie case of discrimination has
    been made. In Kimel, the Supreme Court stated
    that, despite the narrowly-construed "bona fide
    occupational qualification" defense from
    liability under the ADEA, "the Act’s substantive
    requirements nevertheless remain at a level akin
    to our heightened scrutiny cases under the Equal
    Protection Clause." 
    Kimel, 120 S. Ct. at 648
    . In
    contrast, by providing a broad exemption from
    liability under the Equal Pay Act for any
    employer who can provide a neutral explanation
    for a disparity in pay, Congress has effectively
    targeted employers who intentionally discriminate
    against women. See 
    Gunther, 452 U.S. at 170
    (stating that "[t]he fourth affirmative defense
    of the Equal Pay Act . . . was designed . . . to
    confine the application of the Act to wage
    differentials attributable to sex
    discrimination"); see also 
    Feeney, 442 U.S. at 275
    (stating that where an action "could not be
    plausibly explained on a neutral ground, impact
    itself would signal that the real classification
    made . . . was in fact not neutral"). In other
    words, the broad exemption from liability in the
    Equal Pay Act for wage differentials based on
    "any other factor other than sex," 29 U.S.C. sec.
    206(d)(iv), indicates that the Act is intended to
    address the same kind of "purposeful [gender]
    discrimination," 
    Feeney, 442 U.S. at 274
    ,
    prohibited by the Constitution.
    That the Equal Pay Act is primarily a response
    to the problem of unconstitutional wage
    discrimination against women is made clear by a
    comparison of the Act’s remedial provisions with
    those of several recently invalidated statutes.
    As we noted in Erickson, one of the central
    problems with the ADEA identified in Kimel is
    that "[m]ost age discrimination is rational, and
    therefore constitutional, yet the Act forbids
    it." 
    Erickson, 207 F.3d at 948
    . Having identified
    this as one of the "principal propositions"of
    Kimel, 
    id., we then
    went on to reject individual
    suits against the States under Title I of the
    ADA, in part because the disparate impact and
    mandatory accommodation rules in the statute were
    too far "outside the boundaries of constitutional
    discourse." 
    Id. at 951.
    Prior to Kimel, the
    Supreme Court used similar reasoning in holding
    that the Patent and Plant Variety Protection
    Remedy Clarification Act ("Patent Remedy Act"),
    Pub. L. No. 102-560, 106 Stat. 4230 (1992), which
    authorized damage claims against States for
    patent infringement, was not a valid exercise of
    congressional authority under sec. 5. See Florida
    
    Prepaid, 119 S. Ct. at 2210-11
    . According to the
    Supreme Court, because the Due Process Clause
    only forbids patent infringement by States when
    it is intentional and when state tort law does
    not provide a remedy, the application of the
    Patent Remedy Act to "[a]n unlimited range of
    state conduct" was beyond the scope of Congress’
    powers under sec. 5 of the Fourteenth Amendment.
    
    Id. at 2210.
    In contrast to the statutes at issue in Kimel,
    Florida Prepaid, and Erickson, the Equal Pay Act
    is not aimed at a kind of discrimination (like
    age or disability) that receives rational basis
    review. Under the Constitution, gender-based
    classifications are afforded heightened scrutiny.
    See J.E.B. v. Alabama, 
    511 U.S. 127
    , 136 (1994).
    Once an individual is able to establish the
    existence of a gender-based distinction,
    "[p]arties who seek to defend gender-based
    government action must demonstrate an
    ’exceedingly persuasive justification’ for that
    action." United States v. Virginia, 
    518 U.S. 515
    ,
    531 (1996) (citation omitted); see also
    Mississippi Univ. for Women v. Hogan, 
    458 U.S. 718
    , 724 (1982) (holding that a gender
    classification must serve "important governmental
    objectives" and that "the discriminatory means
    employed [must be] substantially related to the
    achievement of those objectives") (internal
    quotations omitted). In many ways, the
    requirement that parties show an "exceedingly
    persuasive justification" for gender-based
    classifications is more demanding than the Equal
    Pay Act’s provision allowing a party to avoid
    liability under the statute if they can
    demonstrate that the established wage disparity
    is based on something other than sex. Because the
    Constitution demands an "exceedingly persuasive
    justification" for gender discrimination, while
    the Equal Pay Act only requires an employer to
    offer some legitimate reason for a wage disparity
    other than sex, in the great majority of cases
    the Equal Pay Act does not subject employers to
    liability in situations where the Constitution
    does not.
    The fact that the Equal Pay Act prohibits
    little constitutional conduct is significant, but
    the defendants contend that we must also consider
    the adequacy of the legislative findings
    supporting the application of the Act to the
    States. According to the defendants, the
    legislative findings underlying the Equal Pay Act
    address only the problem of discrimination in
    private industry, and therefore do not justify
    the application of the Equal Pay Act to public
    employees. Although we recognize that a review of
    the legislative record can be an instructive
    means of distinguishing appropriate remedial
    action from an impermissible substantive change
    in legal rights, see 
    id., we want
    to emphasize
    that a "lack of support [in the legislative
    record] is not determinative of the sec. 5
    inquiry." 
    Kimel, 120 S. Ct. at 649
    ; see also
    Florida 
    Prepaid, 119 S. Ct. at 2210
    ; City of
    
    Boerne, 521 U.S. at 531-32
    . This observation is
    particularly relevant in the context of the Equal
    Pay Act, where the value of congressional
    findings is greatly diminished by the fact that
    the Act prohibits very little constitutional
    conduct, see City of 
    Boerne, 521 U.S. at 533
    (stating that the kind of limitations reflected
    in the legislative findings inquiry "tend to
    ensure Congress’ means are proportionate to ends
    legitimate under sec. 5" in circumstances where
    "a congressional enactment pervasively prohibits
    constitutional state action") (emphasis added),
    and where the historical record clearly
    demonstrates that gender discrimination is a
    problem that is national in scope.
    In considering the validity of congressional
    action under sec. 5 of the Fourteenth Amendment,
    "[t]he ultimate question [is] not whether
    Congress created a sufficient legislative record,
    but rather whether, given all of the information
    before the Court, it appears that the statute in
    question can appropriately be characterized as
    legitimate remedial legislation." Kilcullen v.
    New York Dep’t of Labor, 
    205 F.3d 77
    , 81 (2d Cir.
    2000). While it is true that the legislative
    record of the Equal Pay Act itself is devoid of
    any explicit findings as to the problem of gender
    discrimination by the States, see Hundertmark v.
    State of Fl. Dep’t of Transp., 
    205 F.3d 1272
    ,
    1276 (11th Cir. 2000), the defendants do not
    contest the adequacy of the legislative record
    regarding wage discrimination outside the public
    sector. Moreover, by the time the Equal Pay Act
    was extended to the States, Congress had
    developed a clear understanding of the problem of
    gender discrimination on the part of States
    through its passage of legislation such as the
    Education Amendments of 1972, Pub. L. No. 92-318,
    tit. IX, 86 Stat. 373 (1972), and its extension
    of Title VII to state and local employers in the
    Equal Employment Opportunity Act of 1972, Pub. L.
    No. 92-261, sec. 2, 86 Stat. 103 (1972). See
    Fullilove v. Klutznick, 
    448 U.S. 448
    , 503 (1980)
    (Powell, J., concurring) ("After Congress has
    legislated repeatedly in an area of national
    concern, its Members gain experience that may
    reduce the need for fresh hearings or prolonged
    debate when Congress again considers action in
    that area."). We believe that this evidence is
    sufficient to support the limited action taken by
    Congress in its passage of the Equal Pay Act,
    particularly given the well-documented history of
    gender discrimination in this Nation, a history
    that is embodied in the Supreme Court’s own
    jurisprudence. See 
    Virginia, 518 U.S. at 531
    (stating that "skeptical scrutiny of official
    action denying rights or opportunities based on
    sex responds to volumes of history"); 
    J.E.B., 511 U.S. at 136
    (stating that "’our Nation has had a
    long and unfortunate history of sex
    discrimination.’") (quoting Frontiero v.
    Richardson, 
    411 U.S. 677
    , 684 (1973)); see also
    Crawford v. Davis, 
    109 F.3d 1281
    , 1283 (8th Cir.
    1997) (arguing that it would be difficult "to
    understand how a statute enacted specifically to
    combat [gender] discrimination could fall outside
    the authority granted to Congress by sec. 5").
    After examining the remedial scheme of the
    Equal Pay Act and the legislative history
    surrounding its enactment, we conclude that
    Congress validly exercised its authority under
    sec. 5 of the Fourteenth Amendment when it
    extended the Equal Pay Act to cover wage
    discrimination on the part of state employers.
    Our conclusion in this regard is bolstered both
    by the Supreme Court’s own distinction in Kimel
    between age and gender, see 
    Kimel, 120 S. Ct. at 645
    ("Age classifications, unlike governmental
    conduct based on race or gender, cannot be
    characterized as ’so seldom relevant to the
    achievement of any legitimate state interest that
    laws grounded in such considerations are deemed
    to reflect prejudice and antipathy.’") (quoting
    
    Cleburne, 473 U.S. at 440
    ), and by our
    understanding of the purposes of the Equal Pay
    Act. Congress enacted the Equal Pay Act in an
    attempt "to remedy . . . the fact that the wage
    structure of many segments of American industry
    has been based on an ancient but outmoded belief
    that a man, because of his role in society,
    should be paid more than a woman even though his
    duties are the same." Corning 
    Glass, 417 U.S. at 195
    (citation and internal quotation omitted).
    Significantly, it is precisely these kinds of
    classifications--those based on outdated and
    inappropriate assumptions about a woman’s place
    in society--at which the protections of the
    Fourteenth Amendment are also aimed. Because we
    conclude that the Equal Pay Act is a piece of
    "remedial or preventive legislation aimed at
    securing the protections of the Fourteenth
    Amendment," Florida 
    Prepaid, 119 S. Ct. at 2207
    ,
    we hold that the defendants cannot assert the
    Eleventh Amendment as a defense to the
    plaintiffs’ Equal Pay Act claim./4
    B.
    The defendants also contend that the district
    court erred in determining that Congress validly
    abrogated the States’ Eleventh Amendment immunity
    under sec. 5 of the Fourteenth Amendment when it
    extended the application of Title VII to the
    States. In our original consideration of this
    claim on direct appeal, we noted that this Court
    has already held the extension of Title VII to
    state employers to be a valid exercise of
    Congress’ sec. 5 authority. See Liberles v.
    County of Cook, 
    709 F.2d 1122
    , 1135 (7th Cir.
    1983); United States v. City of Chicago, 
    573 F.2d 416
    , 423 (7th Cir. 1978) (holding that Congress’
    extension of Title VII’s protections to public
    employees was "clearly rationally related to and
    consistent with ’the letter and spirit’ of the
    Fourteenth Amendment"). We then held that the
    defendants had waived this argument, and
    consequently any challenge to our existing
    precedent, by failing to adequately develop it
    before the district court. See 
    Varner, 150 F.3d at 717
    n.14 (quoting United States v. Berkowitz,
    
    927 F.2d 1376
    , 1384 (7th Cir. 1991)) ("We
    repeatedly have made clear that perfunctory and
    undeveloped arguments . . . are waived (even
    where those arguments raise constitutional
    issues)."). Because we do not believe that
    anything in the Supreme Court’s remand order
    necessitates a new analysis of this question, we
    again hold that the defendants failed to raise
    their Title VII claim sufficiently before the
    district court, and have therefore waived that
    argument for purposes of appeal.
    III.   Conclusion
    Having found that the extension of the Equal
    Pay Act to the States was a valid exercise of
    congressional authority under sec. 5 of the
    Fourteenth Amendment, and having determined that
    the defendants waived their sec. 5 challenge to
    the plaintiffs’ Title VII claims, we AFFIRM the
    decision of the district court.
    /1 The defendants no longer dispute that Congress
    unequivocally expressed its intent to abrogate
    the States’ Eleventh Amendment immunity in the
    Equal Pay Act. Furthermore, the Supreme Court
    addressed this issue in Kimel when it stated that
    the enforcement provisions set forth in 29 U.S.C.
    sec. 216(b), which authorizes private suits to
    enforce both the ADEA and the Equal Pay Act,
    "clearly demonstrate Congress’ intent to subject
    the States to suit for money damages at the hands
    of individual employees." 
    Kimel, 120 S. Ct. at 640
    . We therefore do not address the defendants’
    original claim that the Equal Pay Act does not
    contain an unmistakable expression of Congress’
    intent to abrogate States’ Eleventh Amendment
    rights.
    /2 Although the defendants do not renew their
    argument that the Fair Labor Standards Act
    ("FLSA"), 29 U.S.C. sec. 201 et seq., which
    contains the Equal Pay Act, was an invalid
    attempt to abrogate the States’ sovereign
    immunity under the Commerce Clause, we want to
    reaffirm our original holding rejecting that
    claim. Although Congress explicitly stated that
    the FLSA constituted an exercise of congressional
    power under the Commerce Clause, see 29 U.S.C.
    sec. 202(b), we do not believe that Congress
    expressly relied on its Commerce Clause power
    when it extended the FLSA, and consequently the
    Equal Pay Act, to the States, see Timmer v.
    Michigan Dep’t of Commerce, 
    104 F.3d 833
    , 838-39
    n.7 (6th Cir. 1996) ("We believe that th[e]
    legislative history [of the Equal Pay Act] falls
    far short of constituting an ’express statement’
    of congressional intent."), or that any reliance
    on its commerce power was intended to be
    exclusive, see Mills v. Maine, 
    118 F.3d 37
    , 44
    (1st Cir. 1997) ("[O]ne cannot read Congress’
    statement regarding the [Equal Pay] Act’s
    validity under the Commerce Clause to indicate
    that Congress intended to exclude other
    applicable constitutional bases for the Act.")
    (quotations and alteration omitted).
    Because we remain unconvinced that Congress
    clearly expressed an intention to proceed under
    its commerce power when it applied the Equal Pay
    Act to the States, the key "inquiry is whether
    the objectives of the legislation are within
    Congress’ power under [sec. of the Fourteenth
    Amendment]." EEOC v. Elrod, 
    674 F.2d 601
    , 608
    (7th Cir. 1982). Under this standard, it is not
    difficult to conclude that the objectives of the
    Equal Pay Act are within Congress’ powers under
    the Fourteenth Amendment. The purpose of the
    Equal Pay Act is to prevent arbitrary gender-
    based wage disparities, while prohibiting
    "arbitrary, discriminatory government conduct .
    . . is the very essence of the guarantee of
    ’equal protection of the laws’ of the Fourteenth
    Amendment." 
    Id. at 604.
    We thus conclude that the
    Equal Pay Act’s prohibition on discrimination
    fits within the objectives of sec. 5 of the
    Fourteenth Amendment, and that the Act is an
    exercise of congressional power under sec. 5.
    This does not mean, however, that Congress’
    action in subjecting state employers to the Equal
    Pay Act was a valid exercise of its authority
    under sec. 5, a subject which is addressed infra.
    /3 Although the Equal Pay Act constitutes a separate
    act of Congress, it was originally enacted in
    1963 as an amendment to the FLSA. In 1974, the
    Equal Pay Act was applied to the States by virtue
    of an amendment extending the protections of the
    FLSA to state employees.
    /4 In so holding, we join the other Circuits who
    have considered this issue in the context of the
    Equal Pay Act. See Kovacevich v. Kent St. Univ.,
