I'd prefer we treat prisons as mini-societies. Only a minimal set of rules should be set and enforced by the guards. The majority of the rules should be voted on and enforced by the prisoners themselves. Guards would step in if things go awry, but in general there would be a strong incentive to cooperate and contribute as that would be the primary indicator that the prisoner is ready to be released and can contribute to society outside the prison. This should make prisons much more self-sufficient and less costly.
