> Many women still hold on to the idea of finding a partner that is wealthier and more educated. This is due to the past (over)reliance of their partners for stability. But this is no longer true.

I'm not sure this is absolutely true - at least for Germany. Here the figures show, that women and men, ceteris paribus, earn pretty much the same (+-3%). Until... children come into the mix. The lack of child care and societies view on parental leave (for men at least) means, that generally speaking the woman stays home to take care of the child and later on moves on to a part time position thus earning less and having to rely on the partners income again.
