Of course, on this topic of Xi Jinping's wealth alone, I perhaps could have done more research to the claim I was making. However, you failed to adress the other topics, in which I have massive amonts of proof to support, but no, you had to choose the single claim you likely knew it would be hard to prove.
"At this point, your arguments don't sound much different than anti-communist liberal slander against China."
What are you talking about? A Liberal would not care about billionaires, Socialism, and all of the things I am critical of China for, if anything, they would militantly support the present State-Capitalist economy of China. I would argue that China itself is an Anti-communist regime, considering the fact that they have turned away from the goal of moving towards a Communist society, and have completely distorted Marxism to fit its leaderships' own personal goals of self-enrichment. That is not to bring up the fact that China constantly sells firearms to Anti-communist government to kill real Communists in India, Nepal, and many other countries.
Marx and Lenin would be disgusted by the economy of China; all the labour abuses, exploitation, and revisionism. Therefore, if you are a true and educated Marxist, it would be Anti-communist NOT to be critical of China.
