The quote is “from each according to his abilities, to each according to his needs,” Mr. Marxism expert.
Was capitalism built in a day? Do you think that Xi can just press the communism button and make everything instantly perfect everywhere? That’s not how it works. China is currently doing the USSR’s (and Stalin’s) NEP, but they’re doing it so much harder than Stalin ever did. They are literally hanging the capitalists with the rope the capitalists are selling them. Once the forces of production are built up to a point where everyone’s necessities are met—and once the USA is no longer in existence—it will become possible for the world to move forward into the next stage of history.
Also I like how you didn’t answer the question about Marxism being taught to Chinese students. Because there is no answer. Because you are wrong 😉
