No, this is wrong on all accounts. The fact that over 90% of people support the system and believe it to be headed in the right direction, the fact that the large firms and key industries are publicly owned, and the fact that year over year conditions are rapidly improving for the working class do not support your claims.

There are not "concentration camps." The existence of strikes that additionally break the law do not mean strikes are illegal. Western, state-funded propaganda outlets like the Victims of Communism Foundation, BBC, and Radio Free Asia do not honestly depict the PRC. Wealth disparity is falling in China, and more importantly working class conditions are dramatically improving and have been for almost a century.

You have a very confused and distorted view caused by looking at relatively minor problems as though they are widespread and massive. You also have no evidence backing your claims, other than the idea that strikes exist in China. The working class became the ruling class at the founding of the PRC, and has been since. There has never been a time where capitalists have become the ruling class. There hasn't been a successful counter-revolution.

I think if you want to understand China more, you should at least familiarize yourself with the basics of Marxism-Leninism. You can use my intro ML reading list, or Qiao Collective's SWCC intro reading guide.
