Well the free-market is a-moral, and as humans we much prefer things to be moral; like not letting homeless people die or not letting banks swindle retirees. In limited situations, concentration of wealth can produce good things. Pure free-markets have never worked because they've never existed, probably because people don't want them to begin with. Obtain your free-market, socialist, communist, etc policy proposals at the government cafeteria. A well balanced meal is the best meal.
