The problem is not women in general. The problem is single women. Notice how the stats about happiness (and I would bet mental illness) are significantly better for married women.
Its not exactly a newsflash that men do better on average when they're married. We all know the trope about single guys being lazy, dirty, slovenly, unmotivated, sitting around unshaven, drinking beer and eating cheetos in their underwear rather than being productive. That trope exists because there's truth behind it. Well it turns out being alone and without a family isn't good for women either....shock shock.
So when did marriage rates really plummet? What caused it? There's your real problem right there. Encourage and incentivize young people to get married and have a family and a lot of your problems will go away.
Cultural Marxism caused it.
And it was originally seeded by subversive Communist agents literally sent to the USA as proven by the great McCarthy.
Now not sure, I think the ideas have taken hold and are organic.
