When the federal government spends far beyond the tax revenues it has, it gets the extra money by selling bonds. The Federal Reserve has become the biggest buyer of these bonds, since it costs them nothing to create more money.
This new money buys just as much as the money you sacrificed to save for years. More money in circulation, without a corresponding increase in output, means rising prices. Although the numbers in your bank book may remain the same, part of the purchasing power of your money is transferred to the government. Is that really different from what Cyprus has done?
