There are only two kinds of people who give a shit about the supposed "birth rate crisis":

Religious conservacucks who are too married to the idea that "big families = good because, uh, THEY JUST ARE OKAY". That includes the stormniggers who won't shutup about india and africa outbreeding everyone.
Their only solution is to wag their fingers at young people and shame them for not pulling themselves up by their bootstraps. They want to fix the world one internet argument at a time.

The other group that cares are the absolute insane chuds who believe in some great societal collapse because of their fanciful storybook understanding of economics and demographics. Their solution is to post absolutely insane, pie-in-the-sky authoritarian solutions like mass population moves, genocides and violations of human rights. (usually women's rights)

I can see this thread is hosting a healthy mix of these two groups.
