Back in the 1970s, when I was teaching a class of teaching methods for teaching social studies, I ysed a simulation called "Starpower" -- a simulation disguised as a game. In the simulation players were to trade tokens among other games, but the game was stacked in favor of one group from the very beginning. As the game went on, they accumulated more "wealth" their behavior became for domineering. When given the opportunity to change he rules, the group given the advantage always changed the rules to increase their advantage and control -- just like the Republicans in Congress are doing today. Each time the game was played with a different group new to the game, the behaviors of both privileged and disadvantaged changed depending on what transpired. It was a fantastic teaching tool.

If you can find the simulation today, buy it convent a group of 8 - 10 people, play the game and watch what happens. Again, the name was Starpower."
