Mmmmm, if humanity doesn't get babies for say 40 years in a row, we'd be extinct
If humanity wouldn't have babies for say Even 5 years, it would have enormous disastrous consequences for almost all of us
It's actually really important for all of us (even for the ultra rich, but also the ultra poor) that people have enough babies. China knows what I'm talking about, they're heading for a huge population crash
Same for south Korea, same for Germany
