I have run across a number of ideas, both real and fictional, that are either thought provoking, or inspired, hilarious, all of the above, or on rare occasion, flat out brilliant. One funny one that comes to mind was from an old Dr. Who episode, I believe. The setting was some planet similar to earth but with entire planet ruled by an elected dictator - a single person who had absolute power, until election day. When his term of office is up, he is held accountable for his actions by an electronic vote of the people; world wide, and in just minutes [or hours at most]. The dictator sits in a chair, on camera, with the entire planet watching while they vote. If he receives more than 50% of the vote, he remains world leader for some number of years. If he is voted out, he is vaporized on the spot.
