" looking for partners similarly successful, and are less interested in propping up the emotional life of the emotionally stunted young men our society turns out."

There's no need to use such angry and charged words when a single word suffices: "Hypergamy".

Female education is the absolute decisive and consistent factor across all societies in suppressing marriage and fertility rates, for good and bad. It both takes away prime fertility years, as well as raises female expectations (Because females always prefer a higher status/earning man than themselves).

So the more females earn, the fewer males they can accept emotionally. Hence the general collapse of marriage/fertility rates when this happens.

This phenomenon is very good for developing countries, preventing catostrophic malthusian booms. Even Muslim countries like Bangladesh and Saudi Arabia now have normal and sustainable fertility rates. For highly developed industrial economies, like South Korea, China, or most of the west, its terrible in the other direction.
