Financial assets is far too broad a category, but "markets can remain irrational far longer than you can remain solvent" isn't some new statement. I'd argue that this is more a consequence of a confluence of factors including the end of general scarcity of capital, low interest rates, and low taxes.
Medical and Education costs are structural issues within the US, see most of Europe for a counter example.
As far as outsourcing, well that has lifted over 1 billion people out of poverty...so yea, I got nothing for you if you think American's being able to buy more goods for fewer dollars while simultaneously making the world a better place is something to be concerned about.
And our economy is far more stable today then any time in the history of the US. Or are we going to pretend that multiple depressions didn't happen in the late 19th and early 20th centuries? The only reason that the 2008 recession was as bad as it was, was because of a lack of political will to spend money.
The real demonstrable alternatives are those we had prior to eliminating the gold standard. We are now able to print our way out of recessions, at the cost of an incredibly destabilized economy comprised of asset valuations that are so high they lead to perfect correlation downward when there is a shock to confidence.
