Notice a few things:
1) This official Government provided CPI inflation calculator only goes back to 1913. Before then deflation was the rule, and deflation is negative inflation. The Federal Reserve took over money creation and oversight in 1913.
2) To achieve one dollar of equivalent buying power to 1913 it requires the expenditure of $23.21 today. That means our own Government is admitting to todays dollar having lost 96% of its value vs. 1913 dollars.
3) Since 1971 when Nixon took us off the gold standard and left us with a only a standard of "good faith and promises", the dollar has lost a whopping 82.4% of its value (buying power).
Need I mention that one of the mandates of the Federal Reserve is to maintain and sustain the buying power of the US Dollar? I'd say it has failed miserably.
