China is facing a huge problem of domestic migration away from the poorer country-side and inland/western regions to the more developed coastal cities like Shanghai, Beijing and Shenzhen. The numbers are estimated at around 243 million additional city-dwelling residents in the next 15 years [1].
China already has a troubled system of individual registration (Hukou) to limit this migration, however people are still migrating even though the destination cities do not offer them healthcare, education or any worker protection due to their lack of a local registration permit.
China has to make some big bets on how to best provide enough extra capacity to absorb this huge migration of people. Any western country that has successfully managed the domestic migration of 240m residents into their cities without planning or capacity problems should step forward and offer some practical advice.
To use a software analogy, they built a costly application, shipped without any debugging or testing.
