In fact, the operation of a hypothetical free market has never really been the issue. Markets have never been “free” in the normal sense of the term, nor will they ever be. They have always been, and will always remain, subject to external constraints — legal, political, cultural, religious. The question is to what degree and for what ends these controls operate. Purely free markets exist only in the ethereal regions of laissez faire economic theory, along with such treasured notions as perfect competition, freedom of choice and the “invisible hand” that guides the market to produce the optimum outcome for all through the unrestricted pursuit of self interest.
