QE is a backhanded kludge to implement MMT. A more efficient way would be for the legislature to spend federal dollars on needed infrastructure, health care, education, investments that support wages and promote future growth. The Fed was forced into QE by a post great recession economy that desperately needed demand support and a Congress that refused to do stimulus of any kind. The problem with QE is that most of the capital released there stays with the large holders of wealth. While some trickles down most is used to speculate in the shadow banking world, to buy up equities and real property, and not to raise wages.

So long as low wages keep demand low it's hard to get much inflation, and of course, given the massive productive capability in global markets that is basically under utilized, supplying increased demand is not a hard mountain to climb. It WOULD take more capital investment, a slower "get richer" plan than keeping capital off of Main St. and instead playing casino gambling with the other high rollers in that shadow finance world and the equities/commodities casino.
