"The market is what the market is," which pretty much means, "let the market decide", appeared to work well for everyone in the past - because markets were more local, or at least kept within a single country. That way, when markets correct towards median incomes in a reasonably wealthy country, that was a good thing.
The problem today, however, is that this growing global economy with increasingly invisible borders (and enforcement) is putting Americans into a WORLDWIDE middle class. That means a significant drop in economic opportunities for the remaining middle class Americans as more foreign money comes in and snatches up assets here by more and more foreign elites that have squeezed more out of their more submissive and/or uneducated citizens of their countries.
Trade deals like the TPP sound like more of this trend - making the world's elites richer while pushing the rest of the USA'c citizens live like second world citizens in their own country.
So yeah, the free market works today - it's globally working all too well, unfortunately...
