"...and some say than China."

Well, that old one child policy from back in the day may have had lasting consequences?

the problem isn't the policy, it's that when they repealed it China was facing the same issues as Japan, Taiwan, the US, Europe, etc. which is that no one is having kids.

Like Japan never had that law and is still having serious consequences

Taiwan has all the Japan's problems plus higher house price to salary ratio.

I suppose Korea is like that too.
