But there is a much deeper disagreement. Except the powerful who dominate our supposed representatives do anything and everything to keep their power. Such is human nature. It is a failing of capitalism and communism alike. Economic efficiency can mean high unemployment or diminished services.
Efficiency can mean a lot of things, sure.
Of course not. Economic rationlism can mean war or destruction of the environment. I must disagree. No it doesn't. The cost of that kind of efficiency is far too high to justify the benefit - what the free market does is simply to allow the values involved to balance.
