This nation was far better off when physically fit convicts were required to do hard labor on road crews, construction sites, and farms. Up until the 1960s, the Texas state prison system was self-sustaining because of the proceeds from crops and prison industries. There is no good reason, other than protecting their "civil rights," why this could not be the case again. Let the criminals lift dirt with shovels, rather than lift barbells, and chop wood rather than play basketball.
You'll get no argument from me. Our prisons should not be cruel, but that does not mean they need to be anywhere near as pleasant as they are now. Any sort of amenities, such as TV's and recreational sports, should only be provided as a reward for convicts who fulfill certain requirements.
All able-bodied convicts should be required to put in a full work-day performing hard labor.
Correct me if I'm wrong, but I thought the Attica prison riots were a response to bad conditions and things were made better for the safety of the people who have to work with convicts.
