The big question is how do you re-proletarianize the American working class? It would require an extensive change in the current material conditions, for example, the collapse of Wall Street and the financialized system, the re-shoring of American industries etc. It would require a thorough class analysis into the 21st century American society. The conditions are unique to America - having to also take into account the historical development of its racial discrimination, imperial ambitions, dollar hegemony (financial imperialism) etc. that are very different from other countries.

This is well said. I've been trying to explain to a few budding comrades what you describe here.

My less eloquent attempt was simply American's have yet to feel enough pain from the boot on their neck. The pressure was spread across foreign workers for a very long time. Inevitably, it will come back home. That day appears to be quickly approaching, if it's not already here.
