That chart shows why we get less goods for more money.
All according to plan. Inflation is the great friend of the banking class financial manipulators and the great enemy of middle class savers.
Yes, it's a good chart. I'd like to see a companion chart showing the ever-higher taxation over the years, versus the decline of value of the dollar. They're linked. Takes ever more months to earn money to pay taxes than it did in the past. Taxes includes all types of money taken by government including ever-higher fees that didn't exist in the past. So not only does our dollar buy less, but we have to give up a much higher percentage of that dollar to the government.
