You can't grow infinitely forever. Eventually, you'll never be able to hit the target and it will distort things in really weird ways. Just look at the machinations Jinping Xi has had to pull off just to keep China going. They have had positive GDP growth above 5% since roughly 1990.

I think it's a fair question to ask, but then I'd say you'd have to prove we have reached a plateau.
