See, there's where we disagree. You're looking at capitalism in, basically, a theological bubble.. I'm looking at in in terms of practical application. Our perspectives are so utterly opposed that there's really no grounds for a discussion, because I don't accept your basic premise and you don't accept mine. For me to argue on your grounds, I would have to accept your basic premise that capitalism is a "system of free voluntary exchange." Well, it's that because your theology, or your cosmogony or whatever, chooses to define it that way, and I don't agree with that definition. I'll give you my definition and then you'll disagree with that, and the rest of it will just go around in circles.
I have a pretty good friend who's a Libertarian of your style, and we've discussed these very points many times, And I know *exactly* what you'll say and the points you'll make, and I know exactly the points I'll make in return, and I could cut and paste the entire conversation here, and it would make absolutely no difference for either one of us, so why bother?
I think you should research the Black Codes a bit further. They were inextricably tied to the economic system of the post-bellum South, and were entirely driven by the holders of Southern capital in their practice of capitalism.
