(I prefer the manual labor method. Please feel free to spend a few extra hours a day pulling weeds in the field that provides the prison's food.)Maybe prisons should become self-sufficient little communities...growing and processing their own food, cleaning the prison and doing the landscaping, building furnishings and maintaining tools/equipment, weaving and sewing prison clothing, making quilts for their own warmth (gotta count up the needles & pins-). I'm sort of picturing monasteries minus the illuminated manuscripts--although art would be a good addition to the scheme! The only downsides I see are greater expense and difficulty in supervision, and depriving non-prisoners of jobs (although jobs would also be created for teachers). I'd like to believe than non-sadistic murderers are like the Morgan Freeman character in Shawshank, growing older and wiser under a beneficent influence even in prison.
