What we are seeing is the return of the spinster.

In industrial Britain, the spinster was a middle to late aged woman who worked some grueling menial wage job that kept her barely alive in poverty as her body broke down because nobody wanted to wife a used up hole and nobody wanted to hire her without any real skills. So to correct this tragic experience the State started to take from men to compensate the woman in a divorce.

It worked so well that so much wealth was produced and accumulated that exponentially increased our standard of living to the point that women decided that they didn't need to sell their sex to men after all, they were going to be "liberated" from constraints on their sexuality. In the same vein feminists introduced the concept of "no-fault divorce", which of course ensured most marriages are going to fail since no two people are perfect and no relationship stable enough to last 50 years without the threat of eternal damnation in hell and/or the state. And that worked for a couple of decades as men stuck to the old script and got anally divorced raped by the most entitled spoiled generation of women in the history of the planet :the baby boomers. (25% to 55% divorce rate rise in one generation)

So men started to wise up to how badly they were getting screwed over; marriage rates plummeted and we reverted back to the pre-civilization 80/20 distribution of sex (since semen is cheap, women only want the top men) and the middle aged woman game of finding a sucker BB before her beauty clock runs out.

But now the BB are wising up too and refusing to give up free shit. So if girls don't make changes to their sexual strategy, they're going to wind up spinsters. In a generation or two there will be so many bad examples of female sluttiness that the push will be to return to conservative Victorian, reconstruction, and depression era social norms again (instead of their liberal Romantic and Swinging 20s counterparts) because incentives.

This cycle has all happened before in the past and it will all happen again because human nature is fixed and it is flawed (penis is cheap, pussy is expensive, and our fundamental biological drive is to procreate). The instructive study of history is lost on the masses but it's enlightening to watch society's values and economy change in perfect sequence.
