In or about I think it was the summer of 2051 in my future fiction project. In the present day we're seeing in real time the collapse of US hegemony overseas; by the late 2030s internal conflicts within the USA's bourgeoisie about how to save the empire, end up causing a second civil war, triggering mass flight from the USA primarily to Europe and Australasia; the 2040s then see many of those who left the USA during the war returning to work in postwar reconstruction, the USA's relevance abroad completely dead and buried, and the experiences of these returning refugees leaving them thoroughly disillusioned. This is what allows for the emergence of a revolutionary industrial proletariat in the USA, with enough strength to end the bourgeois dictatorship once and for all.
