Quantitative Easing, otherwise referred to in the media as 'QE', refers to governments printing money out of thin air in order to stimulate economic growth. The US ended their program of QE in late 2014. The impression this left with many people was that the need for economic stimulus ended.
This also goes hand in hand with the media theme that U.S. consumers have been deleveraging by paying down household debt such as mortgages, credit cards, car loans etc. since the 2008 credit crises. The reality is much different than what is being portrayed in the mainstream media.
