That's because overpopulation is a myth. Sure, there's a limit to how many humans the planet can support, but we're nowhere near that limit. The USA throws away nearly as much food as it eats. Resource availability isn't the issue - resource distribution is. And since when was it uncommon for people to criticize people's reproductive habits? Eugenicists have been trying as hard as possible to keep black and brown people from reproducing for centuries now, and ethno-nationalists view race mixing as a mortal sin. Generally we stick away from these kinds of arguments, due to how morally reprehensible they are. If you think the world was better or easier to manage when there were only 3 billion people on it, that's purely a matter of opinion, but there's literally only one way we ever go back to that population size, and that's through genocide, so no, we don't entertain these ideas.
