Remember this: http://www.businessinsider.com/china-now-spends-125-billion-per-year-on-riot-gear-and-stability-maintenance-2013-5
The country is estimated to have more than 180,000 protests each year and the ruling Communist Party spends vast sums on ensuring order — more even than on its military, the largest in the world.
I will repeat, as I do from time to time, that China is formally a Fascist nation, which is ironic given all the anti-Fascist rhetoric one sees from Communists. The only important different between Communism and Fascism is that Fascism is an almost viable economic system. It only truly works when conquering other nations, as Hitler did with the Ukraine, and China did with Tibet, but it works much better than pretending that people are automotons who are indifferent to their environment, treatment, pay, and autonomy.
Fascism is great for enriching oligarchs, and has been a great boon to the ruling Communists, who live lives of luxury, and are exempt from most of the laws which control everyone else. They are their own class, and one can see why they would institute such repressive measures to protect their class status. One can see, that is to say, if one is amoral, crass, materialistic, and GROTESQUELY hypocritical.
