 But we'll only know with hindsight, I think. Yeah, it's funny. There's that holy grail, that ideal of the economy growing at its potential, which is dictated by long-term forces like productivity and how much the labor force is growing by. That is the holy grail. You never actually achieve it, but that's the effect policymakers are trying to fine-tune or calibrate. It's probably folly because we're always reacting to data that's stale.
