We are speaking socio-economic. Money. Men are happy to provide money to women, woman are more happy with a man that can provide. The linked study specifically tiptoes around it (money earned) and only speaks of "educational advantage", namely prevalence of women in higher education - my point was that college has been feminized, so this isn't a surprise. Women may swing down in the later years, sure, because to rise up the educational/career ladder, takes time it and of itself. Time that females don't have, when maximizing mate selection. Men don't have that problem, old sperm is just as good, which also explains the 4-year on average disparity between men and women's ages. Men like to swing down 4 years, women up. Aligns again with biology, and the preferences instilled in us.
