The PRC is indeed governed centrally by the CPC, the party of the proletariat. Nobody said China was a "utopia," you seem addicted to making strawman arguments. In fact, Marxism is anti-utopian, you continue to make arguments up in order to prove your baseless points. Also, "regime" just means "government you don't like," it isn't a physical thing. Some Chinese people don't like their system, but over 95% approve of their government.

The EU is thoroughly and entirely capitalist. There is no socialism in the EU. Capitalism is a mode of production characterized by private ownership of the large firms and key industries, while socialism is characterized primarily by public ownership of the large firms and key industries. The "right" and "left" that you speak of are only that way relative to each other, when overall they are both on the right. Further, the EU relies on imperialism in order to fund their safety nets. The fact that the EU has a relatively small left and a huge right does not improve your stance.

I really think you need to take a step back and familiarize yourself more with the arguments your opponents are making. You seem to only strawman, you don't actually know what us leftists want.
