Is the Free Market Moral? The way I've always understood it is that it's the denial of economic liberty(the freedom to contract, to produce and to trade, and the right to property) that's considered immoral. Other than maybe some extreme market fundamentalists, I don't think there's very many economists or philosophers who hold that all economic actors are always entirely ethical and virtuous in their dealings or that market outcomes are inherently just and fair. According to market fundamentalists the only legitimate intervention in markets is the prosecution of coercion, fraud, and theft, everything else should be left for the market to sort out. For me that seems a bit too permissive because there are plenty of more subtle and sophisticated ways of cheating and exploiting people that are just as harmful as coercion and outright theft.
In my view denying people a reasonable degree of economic liberty is deeply immoral as it's a violation of fundamental human rights, but allowing unfettered capitalism to be the driving force in our world and the ultimate power over our lives would be no less so.
