in 19th-century Britain:
'The road to the free market was opened and kept open by an enormous increase in continuous, centrally organized and controlled interventionism. To make Adam Smith's "simple and natural liberty" compatible with the needs of a human society was a most complicated affair.' -- Karl Polanyi, The Great Transformation
PS -- Yes, I understand: That was not a trufry market. But it was the freest market that has ever existed, and it came about through massive state intervention.
PPS -- Don't the people who talk about "under a true free market X would never occur" and "true free markets would not have any Y" ever get a creepy feeling about how much that sounds like Marxists saying that the Soviet Union was not "true communism" and "under true communism there would never be Z"?
PPPS -- Of course, I was one of "those" people. And I was quite sure I was nothing whatsoever like the Marxists who prattle on about "true communism."
