After Lincoln was assassinated, however, the greenback program was quickly discontinued. Repeated popular attempts by farmers and laborers to revive it failed. They were opposed by a wave of banker activism to maintain the banks’ control over the printing of money, which had been established by the National Bank Act of 1863.
In 1872, New York bankers sent a letter to every bank in the United States. The letter, as quoted by Lynn Wheeler in Triumphant Plutocracy: The Story of American Public Life from 1870 to 1920, read in part:
Dear Sir: It is advisable to do all in your power to sustain such prominent daily and weekly newspapers…as will oppose the issuing of greenback paper money, and that you also withhold patronage or favors from all applicants who are not willing to oppose the Government issue of money. Let the Government issue the coin and the banks issue the paper money of the country. To restore to circulation the Government issue of money, will be to provide the people with money, and will therefore seriously affect your individual profit as bankers and lenders .Bank-created money, including paper bills and now electronic money, could be rented to the people at a profit. The people’s debt-free money was limited to coins, which today compose less than one ten-thousandth of M3, the broadest measure of the money supply.
Lincoln’s assassination and the abandonment of debt-free greenbacks marked the exchange of physical slavery for what has been called “debt peonage” or “wage slavery.” Today, as a result, the American government and American people are so heavily mired in debt that only a radical overhaul of the monetary system can free us.
