Genuine question so please don’t hate on me. It seems to me that china now is more of a mixed market than a planned economy. Billionaires and class disparities definitely still exist in China and it seems like american communists almost romanticize china while ignoring obvious flaws in its system, only because they (rightfully) hate america and america hates China. China also supplies all of the world’s exploitative corporations with the vast majority of their goods. While China is probably better than the capitalist economies of the west, I don’t understand why a lot of people seem to hold it in the same regard as the USSR.
Important to note that Chinese billionaires do not control the military, do not have control over the financial system, and you can see that when they start to even speak out too much in public. China is willing to merk billionaires of they don't accept that the CPC is in charge. The party is also able to pursue projects of genuine good that imperial countries would never even consider today.
China might have billionaires, but that seems to be worth something in assuaging the fears of foreign investors from the imperial core. It's notable that in terms of a more reasonable definition of poverty, China is essentially solely responsible for the global decline in poverty from the 1980's on. So they might have billionaires, but they also have Xi Jinping and a party that doesn't give a shit about what those billionaires want for themselves.
China killing billionaires is easily the thing that made me Chinapill
