> The difference is that having a college degree is a more-and-more important requirement for basically everyone not wanting a blue-collar job. I hesitantly suggest that of the people who choose to go into blue-collar work, most are men. (Of the people who go into blue-collar work not because that is what they want but rather because that is simply where their life takes them, I would expect more balanced numbers. I don't have any numbers at all to support any of this.)
