The world we live in, our perceptions of it, the language we use to describe it, is deeply anchored in the technocapitalist empire America was empowered to establish in the unsettled world order left in the aftermath of WW2.
So, what are the alternatives to American hegemony? I don't know. What are the alternatives to capitalism? What are the alternatives to accumulating and hoarding wealth? Not doing that, I guess, right? So, the only answer I'm equipped to provide is that the alternative to American hegemony would be not American hegemony.
(Note: I could definitely articulate a market socialist position here that might reflect my political views but that could and would be picked apart in an Internet forum. The point is that we are all so institutionalized to this hegemonic world that any alternative will be seen as inferior. It will take revolution.)
