Just a note, QE is not really money printing. Strictly speaking, it involves printing money, but at the same time, something very near money is being withdrawn from the private sector; government debt w/ near maturity. That is essentially indistinguishable from money. So called "private sector net financial assets" as the MMTers call it, is not increasing. However the low rates caused by the fed could result in inflation, but it seems in check at this point. If timed right, this could work very well in the short term and have no net effect in the long term.
