I never really get the chance to teach Rawls in my classes, since I’m usually teaching either history or metaphysics and epistemology. But if I did, I think I would assign students to create Rawls’ version of the Monopoly board game.
I think you don’t have to change the game at all to get Nozick’s view of economic justice. Each player has the freedom to invest or not invest, and so individuals have maximal economic freedom. But Rawls suggests that, if everyone starts in an equal position, the outcomes will be just only if the players agree to a difference principle: there can be a change in the economic distribution only if the change makes the worst-off player better off (roughly). So how would the Monopoly game rules change? One idea would be to tax every transaction so that some amount goes to the poorest player. There probably are other more creative changes that could work too.
When I express this idea to folks, they complain, “But then no one would ever win!” Well, that’s the point, isn’t it? Is an economic system just if it allows there to be losers? Especially: losers who lose due to the luck of the dice, and luck of the draw?
