You’re asking a genuine question, I’m providing you with an elaborate answer, and yes, it does answer the question. I could have also summarized the situation and said: “yes, China is still building socialism guided by Marxist-Leninist principles, using state capitalism as a tool with which to boost their productive forces in order to eventually reach ‘real’ socialism”, but then all you’d have is my word without any explanation or substance. The fact that you deem it “too long” isn’t my problem :)
I think this partly has to do with the fact that, historically, material conditions and the availability of consumer goods in the west have been generally better than those of countries where socialist revolutions have taken place (for obvious reasons and through no fault of socialism, “thanks” to imperialist and colonialist exploitation). People lacking class consciousness thus do not immediately see why socialist ideals or even revolution are worth immediate struggle. The rise of China and decline of the West might soon change this dynamic.
