Right now we are between a rock and a hard place. The banks as well as the private sector are sitting on trillions of dollars in cash reserves. If the economy ever does pick up again and that money starts moving then we are going to have massive inflation. So if the economy picks up, we are doomed, if it doesn't pick up we are doomed. All that extra liquidity needs to be put to use or removed from circulation before the economic recovery begins or else inflation happens.
