In 2016, they put an end to the one child policy. In 2017, they are offering women free removal of IUDs. Under the one child policy, women were forcibly fitted with IUDs after the first child, and were forced to undergo sterilization after two.
This has led to a ridiculous situation highlighted in the New York Times, where a woman forcibly fitted with IUDs in 2012, is now being offered free removal of the same IUD.
This is what happens when policy is made centrally, detached from ground realities. I don't know whether there are enough people or not in China - the point was more about the issues with central planning.
Similar U-turns can be seen in the stock market. The government was exhorting people to invest in the stock market as a patriotic duty, creating a huge bubble. When it burst, they tried to manage the stock market by punishing investors who were selling shares! No wonder the stock market has tanked - would you put your money in a stock market where you could be punished for selling?
I agree the Chinese government with its Orwellian-like control of the population can get away with a lot. But they get a lot wrong as well.
