Get into massive consumer debt, go bankrupt, credit companies seize whatever assets you bought and sell them off, continue to live with family, be homeless or get section 8 housing.
You won't breed, or you'll shack up with a girl who is pure trash and game the system. At this point MMT would become the dominant theory, as democrats win elections and republicans are forced to embrace a pro-gibs (but likely anti-immigrationist) policy to stay competitive.
Birthrates for big brains will decrease, free abortions. The goal is probably to discourage births among the plebs, but it'll just be chaos. Bill Gates at 90, living on his million acre ranch in Montana away from you, with a private airfield to flee to his fortress of tech dork in new zealand. The irony of tech nerds 'getting back' at their bullies, but actually just harming other nerdy guys.
