checked and capped > men chase their dopamine in other ways ie porn, video games, weed and lose motivation to go to school, work, or advance themselves in the real world > women get passed around until they age out of the market and can't settle down > birth rates plummet > mass immigration from undesirable cultures ensues to keep up ponzi scheme "infinite growth" economy > white men are checked out, women are now getting lit on fire on subways in cities that could be utopias > we are here this is why op said this is a civilization-ending development. honestly, if immigrants of similar iq could come here and shore up the birth rate, things might be salvageable (if worse) but that doesn't even happening. across the globe, whenever any population group gets wealthier, the fertility rates plummet. ultra-orthodox jew women in israel (a very very tiny demographic) are literally the only exception to this. fertility is low in all western countries plus all high income eastern countries like japan, china, korea, etc.  when mexicans, pajeets, africans move to the usa and become middle class, their birth rates plummet too. immigrants actually can't save our economies beyond 1 single generation, then you just need more immigrants. birth rates also plummeting in mexico and india as those countries develop economically, so there will not always be infinite migrants to move here even if we wanted them to. many of us are in our 30s here, by the time we are in our 60s, if we haven't had the apocalypse, society will be horrible. cities will be glorified old folks' homes while young people will have a quarter as many bars and entertainment options as we have today. it's gonna get so fucking weird at the very least
