This is such a weird take. Sure, when all currencies go down together, the central banks get to pretend to us that their value has not changed, but the US is trying to stop the bleeding on the inflation in our country and that leaves the other currencies falling at the rate they normally would, though they may be trying to slow down, and those poor central banks can't pretend that the value of their currencies aren't going to trash (though this still gives the strange perception that the USD isn't trash, but the best shiniest trash ends up being sought after in this world of garbage)
