In other words, pigeonholing them into careers? Girls get to "be whatever you want to, darling". Boys have to make sure they bring home a paycheck and support their family. Why?
Because someone has to raise the kids, and mothers _usually_ but not always take on that role voluntarily. Especially since infants are biologically tied to their mother for food.
My wife is more educated than I, with a masters degree. But she wanted to stay home, work part time, and not have our kids raised by a third party.
The traditional family structure for Homo sapiens has strong biological and environmental roots, which in turn caused "societal traditions". Changing that in a few generations seems quite unlikely.
