Women and minorities tend to shun the majors that lead to the best paying jobs, which lies at the heart of the overall gender pay gap (not the true apples to apples issue, where male/female engineers hold the exact same position but are paid differently.)
What’s important to keep in mind, however, is that the real issue is not about scoring points in a debate. The real issue is about encouraging more women to pursue majors that are of national economic importance.
