The process of getting to the point of being able to make decisions is a lengthy one, requiring years of study and apprenticeship. Not very practical for women.
I'm very curious why you would feel that way. A majority of college degrees are being earned by women - 60%. For masters degrees women are currently in the majority. Current estimates say that in another 10 years, the majority of *doctoral* degrees will be earned by women.
So if women are outstripping men in college, in master's degrees and soon in doctorates, that is a lot of time they have to invest - time men are NOT investing in education. So if anything it seems to indicate it is women - not men - who have the ability to spend that time in study.
