I have a problem with either generalization. I think we, as a society, need to support all choices a family makes (both parents working, or either parent staying home with the kid), and not judge parents for making any choice that works for their family.

I find it very troublesome that you keep referring to women staying home to care for the kids as 'following their maternal instinct' and men working outside at an office as the natural state for men. Saying that "Women define male attractiveness based on his socio-economic status" is downright offensive, and is getting into red-pill incel territory.

There is nothing 'natural' or 'evolutionary' about how we divide up labor in our society. Up until 100 years or so ago, we didn't even have the idea of 'childhood' that we do now. Parenting was not a full time job, kids were just expected to basically raise themselves and tag along while mom and dad did real work. In evolutionary terms, men haven't 'evolved' to work away from home while women raised kids; both parents did work (varying by society type, e.g. hunter-gatherer or farming) to provide resources for the family. Both men and women worked to provide those resources, and kids just hung around. Obviously, women fed babies the first year or two, but after that kids were pretty much on their own.

Your view that men and women naturally live together like a family in the 1950s for all of our history is a great example of a 'just so' explanation for our current gender politics.
