Lots of interesting points there. Based on my experience in Korea, this is only part of the picture though. Rich people have fewer children than poorer people, so just fixing the money will not fix the whole problem. I'm not as well-written as you, so I'll just say it's complex and one should be careful of reducing complex problems to simple interpretations. The current government for instance does not seem to want to acknowledge the deeper problems and comes up with similar quick-fix interpretations.
