Here’s a scary thought experiment: imagine every person on Earth finds a partner, has exactly one child, and lives happily ever after. Sounds fine, right? But that would mean a total fertility rate of 1 — and the population would shrink rapidly over time, and eventually lead to the extinction of the human race.
So the real issue isn’t whether people have kids at all. It’s the number of kids per family. Just having 1 child isn't good enough. In fact, having 1 child should be treated the same as having no children.
tbh I think this situation is completely irreversible at this point
