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.
The oppressed nations here are the First Nations (indigenous peoples), and New Afrikan (black people), with also non-white Latinos to an extent. These nations will need to rise up and secure land and reparations, before there will be any socialism. Since the compradores have a vested interest with the white Amerikan bourgeoisie this will also probably have a proletarian character. These nations will hopefully rise up in socialist and national revolution because they are largely far more oppressed and proletarianized than their white counterparts. Obviously, white working people are also oppressed in this country so a sizable portion should rise up in solidarity for their own socialism. We have to be wary however that these white socialists don’t try to keep Amerikkka with its colonial roots and simply have surface socialism. This, the proposal of the patsocs, would not address the colonial contradiction. This is why there must be both.
