In the US the foundation and contradiction is settler colonialism. This cannot be solved through integrationism, but only national revolution. You can’t pretend there’s one unified working class in this state because the colonial relation hasn’t been eliminated. The white population may have apparently only the bourgeois/prole contradiction, but to deal with the contradictions of the whole landmass there must be national along with proletarian revolution.
We can deal with both simultaneously.
The US state (including captive (mainstream) media) props up both institutionalize racism and the class relation. So if the state is replaced, then that allows for solutions for both to be developed.
I know, I’m just pointing out we can’t do only one.
