Friedman said inflation is everywhere and always a monetary phenomenon; the dollar is stable; the Fed's inflation does not exceed target; yet inflation in goods and services for ordinary mortals continues at a pace greater than the Fed's 2% target. The Fed's earlier experiment with Friedman's money supply model failed, and they long ago returned to interest rate control as their main tool. Was Friedman wrong? Or was he just being impractical in a world awash in dollars, and like all economists, forced to over simplify by assuming we would act rationally. In retrospect, could any economic assumption be more foolish than that!

IMHO:
The Fed fund rate has basically been kept at 0% for almost six years. Inflation is becoming a serious problem in US.
For example, New York insurance companies are seeking to raise premiums by 13% next year.
