Socialism works in China but not in other countries, capitalism works in USA but not necessarily in the ex Soviet countries, i have the strong belief that all what matters is the person to controls the democratic tools, if we talk about people open minded then everything will be fine, if not, then we just die in front of the hospital because we don't have medical insurance. Capitalism or socialism it goes down to the leaders.
It is not socialism that works in China, but its bizarre mixture with capitalism. Many of the highest officials of the PRC are billionaires, how can this be under socialism? No. Therefore, citing China as an example is not very correct. Here rather Vietnam or even the DPRK.
