Alfredo Rafael Habersham Pabon's comment:
"The reason men work these insane hours is because (unlike women) making more money (acquiring more resources) is the way we males ascend in the dominance hierarchy, and appear more attractive to women. On the other hand, a woman working more hours (thus, making more money) have zero impact on how desirable she comes across for men. This also explain why gyms, yoga courses and aerobic classes are full of women, and not many men: Whereas (evolutionary speaking) males are valued as protectors and providers, women are valued in relation to their physical attractiveness, which is nothing but a marker of their reproductive fitness."
Jay Theyme's comment:
"[...] Its definitely true that men who earn money are more attractive to women. Women who earn (or don't earn) well; it really doesn't make a difference to men. They want to see how fit and sexy she is and they don't care if she's an undertaker or a CEO."
What all of this comes down to? Despite how feminists want to destroy the 'social construction' of masculinity and femininity by having women be strong and independent with careers, the nature of femininity still plays its role. Women, in the end, still want families, and prioritize families above all else. The vast majority of women are not cut out for these positions of power--and when they aren't in those positions of power, they are happier. Because women are innately maternal.
When the family is ripped away from a woman, they become less and less happy. And it has really begun to show.
