What could work is giving people convicted a choice, either go to regular jail and serve your full term, or go to a hard labor camp, eat nutriloaf, waive the governments obligation to pay your medical bills and serve a reduced term. Dig holes, fill them in, break big rocks into little rocks 14 hours a day, get the bull whip if you don't work hard enough. Also allow prisoners in the hard labor camp to smoke cigarettes and drink one 16 oz beer per day.
