I've recently discovered the manosphere and while some of it is stupid snake oil, I found this piece very insightful http://mattforney.com/house-always-wins/

Contrary to what some PUA types claim, success in romance isn't really about who you are but where you are. Being the big fish in the small tank is the only way to get female attention in a society with out of control hypergamy.

Which is why if you are attractive to one woman who is more than a 5, you are probably equally as attractive to many women and should gorge yourself. That same 6 who is madly in love with you now will dump you/divorce you as soon as you start losing your hair or get into a rut, and at that point no women will want you. There is 0 reason to invest anything in women long term. In the casino, if you're not the house, you're the sucker.

Which is why the current situation seems awesome for women in the short-term, but in the end, we all lose out.
