I believe some men and women rejected by the other sex because they are not tall enough, pretty enough, smart enough, etc end up with hate of the opposite gender. It’s quite sad and it’s one reason why families are important. weak family structures in the US are contributing to many peoples pain.
I was on track to be an Elon Musk type of guy. When I was young I got sentenced to about half my income for 23 years in MA payable to a wealthy family. At that level today you actually keep less as you earn more because of government health insurance benefits, tax rates, etc. All incentive to earn and be productive was taken from my life. Ruined.
