We so often forget that the USA became a superpower because everyone else was totally crushed in the WW2, so they could just scoop it all up afterwards (which they absolutely did as much as they could).
It seems like things are changing back. History will tell, but the USA is only liked because of its dominance, not because of its morals. IMO. And USAnians have to figure out why “it is not working anymore” (hint: you were lucky and greedy in the fifties, but the luck has ran out since a long time), so good luck to you, it’s usually a bit excruciating, but most countries figure it out.
The species became a superpower because of fossil fuels which allows each person to benefit from energy accumulated over millennia all in one geological eyeblink.
The chaos you are seeing around us is simply what happens when the drugs run out. The tinder was smoldering all along.
Um, do you think we could feed 8 billion people without massive fossil fuel inputs?
