Just in case that is not a rhetorical question:
Historically US inflation has always been low.
(currently 3.7% in US vs 4.3% in Euro area)
The math is (was??) that

  • 10% required bank reserves (now gone)
  • plus, basic interest>basic CPI
  • equals low inflation.

In simple terms
When interest>CPI, a person “wins” buy keeping money in the bank and buying a refrigerator or computer or whatever next year.
When CPI>interest, a person “wins” buy hurrying to buy a refrigerator, a computer or whatever before prices go up.

Because the American economy includes a LOT of energy and LOT of debt the key condition, (interest>CPI) can be difficult to maintain, but so far so good eh?
