Stupid question, but why not just target more immigration? It's not like there aren't enough people in the world.
Having babies first taxes the economy, then eventually helps it. Letting immigrants in now helps now. And they'll probably have babies.
Korea is absolutely not prepared for any kind of immigration. And they've been isolated for so long they really don't know hor to deal with people who aren't from their culture.
The whole point of increasing the birthrate is the youth will eventually replace the older generation.
So the younger and earlier, it's the better for integration / assimilation I guess.
Still think migration it's a short-term solution. Good for filling out some jobs her and there now. But doesn't solve the birthrate problem itself.
They love anything Asian and we are totally unaware of anything related to historical disputes of all kinds. So we would probably grow really cool hybrids...Mexikoreans or Korexicans. I didn't know, but most Koreans I know are tall people. I always assumed all Asian people were short, but that is certainly not the case. So tall people in Mexico do get an advantage.
