Chinese Population Control Backfires

China fertility issues linked to Hukou population registration system.

Interesting to note that the urbanizing migrant labors allowed Chinese manufacturing to last as long as it has. But at the same time, it prevented the Chinese interior from industrializing because their labor went to the coast. Then, the urban migrants got higher wages, thus preventing the interior from competing with Vietnam and now Cambodia. So the Hukou system theoretically could have allowed the interior to industrialize gradually from the coast. But the coastal elites prevented that from happening by allowing migrants unofficially. And now China also got a fertility problem from the social instability of urban migrants.
