In our contemporary world, we're left with bullies in pin stripes and corporate offices. Monopoly, contrary to a popular view, isn't a model of how economies work but an analysis of how they fail. That's not a free market. A free market exists when players can go in and out of the game as they choose, when no one group controls a market, and when the possibilities for development aren't artificially shut down. How to achieve such an economy is another story.
People make economies what they are.
People decide whether to put research money into new solar cells or new oil fields, alternative engines or alternative color tints. Philosophies tell us, for example, whether economies are about cooperating or competing, preserving or exploiting, stewarding or owning, nurturing or dominating. We're not stuck with one brand of philosophy, which means we're not stuck with one form of economy, either. Bringing the two together and seeing how they're linked empowers us to take hold of our worlds and to turn them in different, more productive directions. In fact, this is the direction that economies are already going.
