Quantitative Easing has been used to save the banks. That it has done. Share prices have been kept high as a result, and with Trump causing an expectation of growth to come, optimism is currently high. The problem is that the saved banks are not doing much in the way of lending into the general economy. Things like transportation, gasoline sales, and many other key indicators of economic activity are still at depressed levels making this the longest recession since The Great Depression. If QE keeps being used to save the financial sector, the danger is that inflation will kick in, making the current problems far worse. Ig markets see government debt as unsustainable, the dollar will come under pressure.
There are signs Trump will engineer a boom.
