[Excerpt] At the theoretical level, we conclude that the case for comparable worth rests on the argument that the current distribution of female employees is based on discriminatory barriers which existing legislation have not broken down. If this argument is valid, the desirability of comparable worth depends upon one's perceptions of how the benefits it provides contrasts with the efficiency losses it induces. Given the trade-offs involved, ultimately one's position on comparable worth must depend on value judgments.
