"If the American people ever allow private banks (Federal Reserve) to control the issue of their currency, first by inflation (quantitative easing), then by deflation (quantitative tightening), the banks and corporations that will grow up around them will deprive the people of all property (foreclosure) until their children wake up homeless on the continent their Fathers conquered"
-Thomas Jefferson

The Fed is planning to start unloading their balance sheet, so we're crossing from inflation of the money supply to deflation of the money supply. That's how the Fed created the great depression.
