And, I might add, Allen, I think most of the Austrian School economists are "free-market" ideologues with no concept of reality - that is, with little to contribute to a reasoned discussion. It seems obvious to virtually anyone who thinks - which clearly includes yourself - that some kind of "mixed" economy is required in a functioning society. It is the balance of the mix that is important, and as you note, purists of virtually every stripe are counterproductive.

Here, as elsewhere, people are outraged at what feels like a rigged game -- an economy that won't respond, a democracy that won't listen, and a financial sector that holds all the cards. - Robert Reich
