I don't know why you would hope to come back to the U.S. since you like it better there but sure, come back if you want.
I think there is plenty of awareness of the very real problems in the U.S. Finding support for solutions is hard. Having and inflated sense of worth is not helpful but having a realistic sense of worth is necessary. I don't think policing the world and having proper social policies at home are mutually exclusive. America could do both if the plutocratic oligarchic elites wanted too.
It would be nice of France and Germany did more to counter Russian and Iranian aggression in Europe and the Middle East.
