Men make only 40% of college students.

 This is being deplored,  but I am not sure it is all that bad.  There are a lot of good paying jobs for men that don't require a college degree.  Truck driver, heavy equipment operator, logger, construction worker, auto mechanic, miner, carpenter, cop, fireman, lineman, soldier, machinist, and many more.  Few women want to take those kind of jobs.  Women are looking for office jobs with no heavy lifting, where they might snag a good husband.  Plus more girls are deeply into academic work.  There are a lot of guys who find academic work boring.
