And that isn’t democratic because?

Also lol Wikipedia

Read Rosa Luxemburg on the limitations of unions, you’ll have a better idea on why China prefers their union system.

How do they not meet the standard?

They have a democratic state which owns most of the MoP.

If you don’t think China is democratic, what would they have to do in order to meet the definition?

A democratic state where the proletariat are in control owning the MoP fundamentally isn’t capitalist, “state capitalist” or otherwise. Capitalism requires specific social relations that aren’t met within socialized ownership.

Please read “Imperialism: the highest stage of capitalism” and then explain what you mean.

There was some integration (as second class citizens) and some displacement.

Yes they straight up have displaced Jewish Palestinians.

No, settler colonialism

No country is an angel though, at the same time Britain was intentionally starving Indians and the US had Japanese American citizens (including children) in concentration camps

The US isn’t a democracy though, it is a dictatorship of the bourgeoisie, where every election we get to select which group of oppressors will wield state power against us until the next one.

Also decline is caused by anticolonial resistance and the logic of capitalism breaking down. I would suggest reading Lenin’s “imperialism” and Fanon’s “wretched of the earth”
