The advent of dating apps. Every single girl has been programmed from birth to believe they deserve a Prince Charming so women will all only swipe on the top 5-10% of men. Women just have too many options now, not just guys from class or work or friend groups, but the entire world, so why not try and get with a handsome millionaire? Because these men have all of the options, they'll never commit to a woman, just hump n dump, so women are left feeling used and unsatisfied, yet they don't change their behavior. The other 90% of men are also left unsatisfied as we get very few matches and the ones we do get will generally ghost us.

I don't literally think the government should assign mates to citizens, but modern romance is dead and broken. Men and women have never been more antagonistic towards one another in history, thanks most likely to fourth wave feminism, which has resulted in the "all men are oppressors/trash/rapists" type of discourse. The average millennial man has not been laid in the last year according to a semi-recent study. So men are lonely, spend more time online, and gradually develop mysogynistic attitudes.

#MeToo has also led women to not trust men (harassment, rape) and men to not trust women (false accusations). People are scared to interact. I don't even try to flirt with anyone anymore lest it be construed as sexual harassment. People are so broken they can't connect IRL and are forced to try and keep using dating apps. An example of this zeitgeist was a mainstream horror film coming out a year or two ago about a couple meeting in a grocery store instead of an app and the dude turns out to be a serial killer (fucking thanks, Hollywood).
