Okay, my understanding is that there are classically two classes: the working class, and the bourgeoisie. Only thing I'd add is that there's the "I own means" bourgeoisie and the "I am powerful politically" bourgeoisie. Pretty much always the same, but not necessarily.
"western" democracy improves upon this by making every person have at least some power politically, thanks to everyone being able to promote and run on ideas, this also allows local and foreign powers to amplify certain ideas, which isn't great. Various factors make this system more or less effective at representing the people's will.
As I understand it, the Chinese system of democracy is basically a mirage, because while you can argue it does a better job than any other dictatorship, it still is one, since the people have virtually no say on who the leaders are. I see it as something akin to a meritocracy, where an elite choose other people they deem fit to lead. In this context the CPC are no functionally no different to the bourgeoisie, they just replaced them.
The top-down governance can be good, but it also causes a lot of problems, such as the one child policy that created and still creates tons of problems and suffering.
As for Imperialism, which was mentioned earler in the thread, while the US and europe are undisputed world champions of imperialism, china also does imperialism in it's own borders, with the western provinces.
I am certainly open to being wrong, this is just how I currently see the subject.
