Yes, actually. A lot of professions that are dominated by women (currently at least) require some sort of bachelors degree e.g. nursing, lawyers. Or conversely: the jobs where you can have a good life without a college degree tend to be more male dominated (e.g. blue collar manufacturing).

Oh, those bastard mysoginistic blue collar male manufacturers, keeping the good manufacturing jobs away from females who are forced to settle with being lawyers.

Perhaps men find the trades to be a more viable option.

Ah, I see, so when males are underrepresented in a field it's because they have more viable options elsewhere, but when females are underrepresented, it's because they are being discriminated against.
