Patriarchy still has a stranglehold on us all. Men still want to be big strong "providers" and they want women who are compliant and successful, but not quite as successful as they are. And, more and more this is going by the wayside. A lot of women want nothing to do with marriage or with men. It used to be that women who'd been married before largely didn't want to marry again, but now even young women are realizing this really isn't such a great idea. They will be both expected to be near equal financial contributors and at the same time expected to overwhelmingly care for the home, the children, and the elders. They are more and more saying No.

You may "know many examples" but that is anecdotal. Of course there are women who still buy into patriarchal norms, just as there are men who do, because we've all grown up with it. And what the sociological data says is that hypergamy is largely a myth. It's a hold-over from an earlier time when women weren't allowed to provide for themselves and so they had no choice but to align themselves with a man who could do that well for them. That is no longer the case today.

You've provided no evidence for your theory other than "I just know" and "there are many examples." How about a little substance for your assertions? Sure, women want men who are financially stable and not just going to drain them, but are you really going to tell me with a straight face that the 50% of women who earn as much or more than their partners are really upset about that? Good luck!
