Well, that was Mao’s view.
I think the Cultural Revolution should just weed out the capitalist and reactionary elements in the party, that’s all. The Chinese Cultural Revolution went way too far and did a lot of bad things.
There haven’t been any cultural revolutions (not really anyway) ever since. I guess Stalin did in 1938 but he also killed all sorts of innocent people.
You don’t need constant cultural revolutions to preserve Communism.
As far as Deng Xiaoping’s model goes, China is still a Communist country in a very many ways. It’s market socialism. I think you need a market even in a Communist society. Otherwise everything goes wrong. The market should be used as a tool for harnessing the productive forces. The market would provide a lot of readily available goods, a pricing mechanism, etc. But the market needs to serve society, not the other way around. If the Party is in control, they could use the market as a tool and if any sector of the market ceased to serve society, the Party could step in and modify that sector, take it over or even shut it down.
But there are all sorts of problems with Dengism. Deng got rid of free health care in China. I believe in China, you need to pay to go to the doctor or get medicine. Millions of people are dying in China from lack of healthcare. This is the move that almost the entire world has cheered wildly for – Dengism. Have you ever heard the Western press say one bad thing about Dengism? How bout millions of people dying from lack of healthcare? Why should we cheer for that? What sort of person are you if you cheer for that? Capitalists cheer for stuff like that. Capitalists see millions of people dying for lack of healthcare, and they stand up and cheer. See why I have such a low opinion of capitalists?
Also sexism came back in a very big way under Deng. Men started treating women a lot worse than they did under Mao. I do not know why that is, but capitalism just seems to bring out the worst in people.
Of course the crime rate absolutely exploded under Deng.
