China hasn't been communist for a really long time. It didn't truly stay communist for a long time either, it was more of an authoritarian autarky run by a nutjob.

What is is today is state sponsored capitalism. You have cronyism, nepotism, lobbying and rent seeking. All of which are also found in the US.

China's social spending is far lower than many other developed nations.

I see young people advocating for socialism a lot in Canada, but rarely communism as in communist Russia and communist China. As others have said, old style communism isn't even around anymore. Russia is a fake democracy and China is a strange blend of one party rule and capitalism.

I don't think it does anyone any good to throw around naive and simple terms like communism. Focus on issues like public healthcare, breaking monopolies, basic incomes, and so on. We'll get along a lot better that way.

Go to Shenzhen or Shanghai, if that's what communism looks like, then it has already won. A few weeks ago, when I was in Shanghai, I went for a walk and saw more McLarens and Ferraris in a few hours than I've seen in New York, Berlin, and Paris combined.

They're more capitalist than we (the West) ever were. Communism is basically only something that remains in the name of the party. Their version of capitalism just has a lot more state involvement and capital controls, which lets them plan over longer time horizons more successfully and pivot to new priorities much faster.
