There have been very few “swings” at all. This response is case in point for “so measured it is probably not enough”. Policy has been incredibly stable in the last decade, and then we had a crazy pandemic and the fiscal policy response, in hindsight, was wrong.
I don't even think it was wrong, it just went on too long. The US had an excellent recovery, but because Congress didn't want to pass automatic stabilizers, and they had a hard time passing laws, they set long expiration times- and the last stimulus bill went on too long in retrospect.
