I mean I agree with this, there are too many people. Just some amount of people should still have kids.

It's a bit more complicated then that. There is an issue with many countries being run by absolute psychopaths, particularly in countries where they arrange women into marriages and much of the world's population problems come from those places. In countries like America the birth rate is very stable even metastable. People aren't allowed to talk about that though so the conversation goes nowhere and we just get stuck with increasing racism year by year until democracy breaks, and the system snaps back to reasonable.

People forget that the real reason the west is better than other places is because of the free culture, and the freedom of ideas. That is really the only thing that makes us better than other countries. Now that both sides are into the idea of censoring or straight up blocking democracy, our system is almost certainly doomed.
