Just what I meant. The problem for public schools is that there are a million grads with degrees in social work, poli sci, pyschology, sociology, grievance studies (womens studies, etc), and other fake sciences, many of them ready and willing to be teachers. People with degrees in history or the classics, by contrast, are almost as hard to find as math and science majors willing to work for public school salaries. (Unions being what they are, you can't offer math and science teachers twice what you offer the "social studies" teachers, despite the fact that they're worth it.)
