The problem with so many of these debates about "free market capitalism" is that they hold up the United States as an example. Whether or not you agree with the tenets of free market capitalism, there is no reality-based argument that can reasonably be made that the United States represents anything like free market capitalism. Interest rates are centrally controlled by the Federal Reserve. The use of official federal currency is legally mandated. The FED, the ECB, the BOJ and a variety of other central banks directly purchase their own debt as well as equities, bonds, and financial instruments of all kinds to manipulate and control markets. Quasi-governmental international groups like the IMF and the World Bank exert massive influence over global markets in a variety of substantial ways.
There is certainly a debate to be had over whether or not "free markets" are beneficial or desirable, but to put forth the United States as an example of a "free market" is to construct a straw man.
