I think Jordan Peterson is correct on that one: the real question isn't why women don't go after those kinds of jobs, but why anybody is willing to work so hard and to give up so much for incomes that allow a marginally better life (e.g going from 40k a year to 100k a year is a huge improvement, going from 200k to 300k?).

Also, for women anyway, the kind of work it takes to get to the top effectively means they aren't going to be having babies. A man aged 45 can marry a women aged 30 and become a dad - women who marry younger men aren't more likely to have kids because of it and at 45 it is unlikely for a woman to have kids at all.
