Socializing that cost is a rational response; whether it will work is the question.

I doubt it. People don't have children and bring them up because of rational cost-benefit calculations.

As I said, ultimately the cultures that reproduce will win (barring a nuclear attack).

Then that is saying that the cultures which are most repressive towards women will win since those are the one's with the highest birth rates.
