My friends who are nurses wanted to be nurses, they didn't want to go medical school. They didn't want to wait to make money until their 30's, they considered career paths in relation to having a family. As long as they had the option, I don't see why forcing outcome is important here.
As for helping men into nursing, if diversity is good in one field its probably helpful in another. Men might want a male nurse who can emphasize with male concerns. Being a woman, I'm just taking guesses here, like prostate issues, balding, infertility, and whatever else.
Maybe we should help men get into fields like nursing and teaching. So boys and girls both have role models in lots of fields.
I get the historical context, but I don't think forcing an over reaction in the other direction is better. I think we all benefit from choices and freedom.
