while even people born in Asian countries like me would like to go back 3-4 generations and forcefully reduce birthrates, it is not a problem as simple as it seems.

By that logic Canada, Australia, NZ, and arguably even US are settled places and should not be counted.

I do agree that every goalpost can be moved by drawing the boundary as you wish, but surely the fact that developed countries enjoyed a good standard of living for 100+ years and contributed more for a long time counts for something
