“.... misjudged the strength of the labor market, the degree to which longer-run inflation expectations are consistent with our inflation objective, or even the fundamental forces driving inflation,"
That last part “ fundamental forces driving inflation “ , means DEMAND, or lack there of, the same issue that’s been plaguing this economy since 2008. They still can’t see organic demand , and she’s already said that QE did NOT have the desired effect in that vein, it only increased the wealth gap. So, I wouldn’t be too giddy expecting more QE or other easy money fed tricks. I think it was a rather dire prognosis , like Morgan Freeman “ the Comet is still coming “
Without demand, this economy can not have a boon, and supply side theory has NOT worked to create said demand .
