Communism isn't the issue the same way Capitalism isn't the issue, the issue is rich people abusing working class and poor people. Removing democracy from these systems just make them absolutely horrid in the long run. Also China isn't communist it's state capitalist dictatorship.
How are they communist? Their economy is obviously heavily based on capitalism, no redistribution of wealth. The only thing that lines up is the promise of socializing in the future? Though I don't believe western politicians nevermind Chinese dictators.
How much time have you spent in china? When I worked there they were capitalist as fuck with everyone hustling for themselves ( besides the government being able to force people and companies to do anything they wish)
