Greed sure, but also optics. In the US at least, we love to condemn China for being "communist" and not a real democracy. Remember, for the US, communist has been the number one enemy for a long time. Obviously, we can't do what they do.
But we do what they do, and China isn't even communist.
China isn't communist because they have many free markets sectors of their economy and many private institutions.
People just don't know what communism is. Calling yourself the communist party doesn't magically make you communist. You have to do communism, which they no longer do.
It's a very simple test. Can I own assets, such as a factory? If the answer is yes, you're not communist. China isn't communist.
Having your mode of production focus on people and not profit. Having a dictatorship of the proletariat is the most important thing.
The end of private property is an eventual goal but it’s not close to the primary issue in 2025. The actual fight is against imperialists and global capitalists. Private property can be a tool in that fight. Being revisionist like China still makes you a communist/Marxist.
But we do what they do, and China isn't even communist.
