On the photo is Jack Ma, one of the richest capitalists in China, the owner of Alibaba, the Chinese billionaire who said the working hours of the workers should be extended to 12 hours a day.

Many leftists and even people who call themselves marxists say China is still socialist, while other leftists/marxists say it has nothing to do with a socialist country today. Some people also argue that the reinstauration of capitalism in China, after Mao Zedong, was a treason against the revolution and socialism and there is now a lot of rhetorics to justify this opportunism.

If China is still socialist, as some people advocate, how to explain about the billionaires, capitalists, supposed explotation of workers etc.?
