Regarding current Federal Reserve policy:
This concise little article points up some of the key concerns held by those of us who doubt the wisdom and efficacy of multiple iterations of QE, not to mention promises by the Fed to maintain virtually endless ZIRP:

The author started a very successful fund when he was still in his 20s, and in my opinion shows a fine understanding of the potential adverse consequences of today's policy mix. He specifically mentions the tail risk associated with coupling reckless fiscal policy with unsustainable "jelly donut" monetary policy.
One thing he didn't mention is that we've been on a monetary "jelly donut" binge for over a decade now. Of course, aggressive Federal Reserve loosening started pumping up the housing bubble in the early '00s. With the exception of a brief period in 2006-2007, when the Fed intentionally inverted the yield curve (and suddenly decided that it had to reverse that course), monetary policy has been ultra-accommodative for a long time.
In other words, we've really been on a gargantuan "jelly donut" binge for a full decade. (Of course, if you look around, you'll notice that it seems like that's literally true.)
But metaphorically speaking, for how much longer are we likely to be able to get away with this "jelly donut" monetary binge without producing severe adverse consequences?
