A small amount of inflation (1-2% per year) is required or else you'd get deflation. Deflation is an almost guarenteed death spiral for an economy as everything grindes to a halt because not spending makes you richer.

This is something you might hear in a grammar school economics class, or a Federal Reserve presentation, but I don't think it's a hard fact.

Why are you presenting it as such?

Because it has occurred multiple times in multiple countries. It is a hard fact.
