Not having kids is the only way some of them are gonna be able to afford to live, and less people 30 years from now means they might even be able to afford a place to live if they can retire.
There’s always fearmongering when populations god down, but historically it’s the only time periods normal people can claw back some wealth from the 0.1%
Which is why the wealthy always freak the fuck out. They do t care about people, they care about labor supply, and the more people the cheaper labor.
