The prison I was at was in the country and had its own Dairy farm and piggery. Some inmates worked there.
Others got Highway detail (picking up trash on the roads, mowing and weed whacking the exit ramp areas).
Beach detail (picking up trash on the beaches at the shore)
Some were on work release where they had real jobs in factories or McDonalds. Letting them have some responsibility and giving them something to do is a motivator.
Great to hear it Jersey Repub. Biker Chick!
Plus it gives the inmates skills when they eventually leave prison (some may actually like the work and go into agriculture ;)).
In general, when people are caring for something or someone else, they are more likely to get rehabilitated. This is true whether the thing cared for is a couple of piglets or a tomato patch.
Lieberals can never figure out why giving the criminal class or the homeless class somebody else's money just doesn't seem to motivate them. They just think it is because they can't spend enough or do it often enough.
