Free market enthusiasts' reasoning is literary the same as Communists': when their grand theory fails to deliver its grandiose promises, it's nver because their believes where nonsensical, but because “it isn't real Communism/free market”.
Seems pretty reasonable to me. Is your contention that we _have_ achieved some pure form of free markets or Communism?
Totally, tons of govt. regulation and interference is what defines a free market. /s
Communist regimes, especially the USSR, had nearly unlimited power to impose exactly the policies that supposedly would help.
Open societies, in contrast, must balance many competing interests and voting factions, meaning that free market supporters have limited power to enact their preferred policies, meaning they rarely can be implemented in a “pure” form.
