Suppose that we have two possible prison systems, and you as judge may sentence this convicted bank robber to either: One is Attica, where he will suffer terribly during his eight- year incarceration, and come out unreformed, or maybe worse; the other is Shangrila, where the robber will enjoy interesting work, learn important skills, live a decent and not unpleasant eight years, and will be very unlikely to return to crime. You may think that actually the opposite would result; put that aside for a moment. In this situation, which would you choose for the sentence you impose?
