I agree that men now have problems. But the difference in rates of male and female college attendance and graduation rates is a consequence of rational, self-interested choices by both men and women.

On the average, for a woman to earn as much as a man she has to be roughly one notch above him in educational attainment. To earn as much as a man who hasn't completed college she has to have a degree. Moreover occupational sex segregation hasn't diminished since the 1990s. While college grads compete in a unisex labor market for jobs in management in the professions, the market for jobs available to the other 2/3 of the population are highly sex segregated. There are still lots of non-college grad jobs for which I as a woman would not even be seriously considered and the repeated suggestion that this is solely a matter of men and women having different preferences is questionable given the natural experiment of WWII when women flocked to Rosie Riveter jobs once the word was out that they could get them.

Good thing for me because if I could get a decent blue collar job I would never have gone to college much less grad school. I would much rather be a garbage collector than a supermarket checker and much rather work construction than be a secretary. Without a college degree men can get decent jobs but without a degree most women are still de facto restricted to low-wage, pink-collar drudge work. I agree that the male/female difference in college majors and college grad jobs is largely a matter of choice reflecting different preferences and aspirations. But that is not so for most jobs available to individuals without a college degree.
