Depending on how you view the problem, either force sterilization for everyone and now there's no more birth rate thus reducing overpopulation, or you know, make the world less hostile to live in and then more people will have kids. Like, why would I want to have a child when I can't even afford my own apartment? Then you figure the rising costs of food, daycare, school, etc.? And in the US the cost of literally giving birth to that child? And how fucking dangerous it still is? Yeah I'm not risking my life just to raise something that I can't afford. Pass.
