I don't directly recall the details of Friedman's argument, but I think there are two differences between what you said and what he would argue. First, and perhaps crucially, he points out that economic freedom is necessary but not sufficient for political freedom. His stronger, more central argument is that if a central entity controls the means of production, it can at will impede the free flow of ideas. Therefore, then, to ensure free flow of ideas, control of the means of production must be distributed and private. Second, and I think this is much more similar to what you said, (I think he'd say) there's a psychological component to economic freedom as well. If the government does not impinge on a person's economic decisions, she'll become unused to the idea of the government dictating with whom she can associate and what she may or may not believe.Archaic` wrote:The idea that greater economic freedom leads to greater political and human freedom is, I feel, a central argument of any stripe of libertarianism (even the wackjob ones). The concept is basically that if a person is relatively poor, they're going to focus their efforts on essential needs first and foremost, namely shelter, food, and water. It's asserted that greater economic freedoms should lead to greater economic prosperity over the long term. The newly prosperous then, now that they no longer need to worry about their essential needs, can and will focus their efforts on acquiring their psychological needs, namely the demand for greater political and human rights.
I'm not contradicting that what you said is an essential component of libertarian rhetoric, I'm just adding some additional arguments and nuance.
