Interesting - thanks for the link. So in ~1980 it was pretty much the opposite that it is today. By 1990 they had balanced out to close to 50/50 and then a slow slide to where it is today.
I read the Time article when it came out. It’s still a zero sum game across schools though. The number of males going into higher ed is decreasing because they’re finding quite viable employment opportunities without spending $100-300K on an formal higher education (never mind the opportunity cost of 4 years of lost income). The solution might be to figure out how to get more women into the trades.
