When the economy can stand on it's own without these crutches, only then is it 'healthy'.
And IMO, that will never happen.
I believe that the first Q the Fed ends QE once and for all and starts to raise interest rates the economy will collapse (how far, I do not know).
I believe the economy is a mess...with the Fed indirectly propping up equities (and making the rich, richer) whilst the rest of the economy outsources to other countries and trades in quality full time jobs for lower paying part time ones because the Fed/federal government refuses to allow prices to reach their 'natural' reset levels from the skewed prices just before the housing bubble burst.
It is the Mercedes-McDonald's recovery...and it's powered by debt (as opposed to solid fundamentals).
And IMO, it's a mirage.
