Look at men in the past. It’s against men’s evolutionary nature to marry yet they still got married just as quickly (and they didn’t need wives to support them). So your argument that women are taking a role traditionally held by men before and hence aren’t marrying doesn’t seem to hold water.
Here’s the problem: The feminist narrative currently out there is a myth. It says women were always kept down and only now are rising to positions of power. But look at history and you’ll see there were women in positions of power going back thousands of years (Most pre-industrial societies gave power over a nation to the Queen if her King died first and societies like the Egyptians were ruled over by women even without men)
To me this seems like a societal misfire. It seems like the majority of women in the past wanted to stay home and take care of their family (as evolutions suggests they do). Then that became their accepted role and the minority who didn’t want that felt trapped in their circumstance. They became the original feminists and rightfully won the ability to do whatever they want. Then the next generation feminists developed some kind of resentment towards women who did stay at home and attacked them. So now we have a society that has forgotten how valuable housewives were and in doing so has created a value system in which women who want to be housewives are told their inferior to those who don’t. But the housewives were the ones who were driving most men to get married.
So with women feeling they’d be inferior to want to be married with a family and men screwing everything that moves (as evolution has taught them to do) we have a society where no one’s pushing marriage (and I think we’re worse off for it)
