A lot of Korean stock buyers are deranged gamblers who'd feel right at home at r/WallStreetBets, and even they are tuning out of America's shit.
USA is no longer a superpower, they just haven't noticed it yet.
Well, I feel sorry for the first country that tries to test that theory.
One can make an argument the global dollar is losing its hold, or that the world is expanding away from US trade, which are both objectively true.
But to say the US is not a superpower is rather foolish.
