I wonder if we need UBI to stabilize the birthrate. Basically if people have some assurance that their kids can be supported and have decent prospects in life then perhaps they will have more kids.
Also, our big cities have evolved to serve adults vs children. We have a proliferation of services for adults: sit in restaurants, cafes, coffeehouses, etc… Just look at turnstiles to the subway and the stairs you need to ascend/descend. Good luck trying to push strollers or drag children around in our urban areas.
For Korea it's not about UBI but about terrible working conditions and societal pressure.
Even with UBI you want your children to go to the best schools so they can get a job at one of the Chaebols.
Koreans still have a culture of face.It's hard to admit that you live on just UBI and cant hang around your friends in places where you cant really afford to be.
