well, it's a bit worse for some countries. South Korea, for example, is already doomed. they've passed the point of no return and can't reverse the population collapse. I'm not a person who is educated enough to give a guess as to what that will mean for them in several decades, but I imagine it's nothing good. the country likely won't survive as it is now.

China can still avert disaster, but it's still gonna be uncomfortable for them until that aging population starts, well, not being there anymore.
