First off lesbians exist.
Secondly women didn't really choose who they 'mated' with, it was chosen for them. Thirdly women who did chose, which was very rare, usually did due to the fact they could not work themselves, the only way to make sure they were financially secure was to marry well. Finally the fact people exist who are descendents of slaves or the poor means women did have relations with poor men.
You sound like an incel who's listens to, to much black pigeon
There is no weaker sex, there is no biological drive, plenty of women date down, as you put it, especially in the modern era when women can train, get educations and work with out being banned by men, in fact I am one of them, the thing is I don't treat myself as dating down, and I don't see my partner as lesser than me, I have a master degree and work in the historical sector, my partner makes boxes in a box factory, I don't see him as any less than me, to me he's a hard working man. I'm not the only one I know many women who have partners who have no education, earn less or are not as intelligent.
This incel/mgtow sexism is just an excuse men use to 1/stroke their egos, no men aren't the better sex, women aren't the weaker 2/ make excuses for their own failing.
Lastly women are not weaker due to needing men to provide, the fact is society ( which was run by men) banned women from education, leadership roles and working, using things like religion as an excuse. In fact it has been discovered women were likely the inventors of agriculture and farming due to them being the gatherers, they realised they could plant and harvest themselves making life easier.
