It is the paper money created out of thin air that creates the unfair distribution of wealth that is making the middle class fall more behind and the poor more poor. Newly created money and credit in a paper money system benefits those that can access the money first and buy capital goods and real property at one price before the new money circulates and makes all prices go up. Wages also do not keep up with inflation and that creates another squeeze on the middle class.
Historically, the United States has been a hard money country. Only [since 1913] has the United States operated on a fiat money system. During this period, paper money has depreciated over 87%. During the preceding 140 year period, the hard currency of the United States had actually maintained its value. Wholesale prices in 1913... were the same as in 1787.
