women who stay home and raise children have less savings than men
You know, in Japan it is standard for men to give their paycheck to their wives. Their wives do the household budget, pay the bills, and give their husband an allowance. As a result, often women have much more savings than men in Japan and find themselves in much better financial shape in the event of a divorce.
I see the incel movement as nothing more than MAGA-lite. Instead of offering any solutions to anything, Andrew Tate has just told them that it's ok to be mad and moreover, the target of your anger should be woman. Not much different than the messaging of any autocratic movement, like the MAGA one. Nothing will ever be solved by this kind of thinking. The only result will be more hatred.
De Beauvoir sounds like an interesting thinker. I've never been exposed to her, though that is probably unsurprising. Interestingly, the way you break down her ideas makes me think of Carl Jung.
