The problem with self sufficient prisons is they soon become cheap labor factories in which people are jailed so as to increase the amount of cheap labor. And then these are in competition with others that have to pay full price...it all gets convoluted...and could be an interesting topic for another thread...
That's possible, wil, but no worse than the current prison-industrial complex. Already the jailing-for-profit game is quite lucrative. I wonder how much the Dow Jones Industrial Average already depends on that to keep afloat and prospering.
Perhaps if the prisons were closed systems, as much as possible, it would be better. Like with the food, that wouldn't be sent outside the prison. It would be consumed right there. The benefits of an organic vegetarian diet for the prisoners would be an added bonus. Or forget that, have them raise chickens and pigs and cows, too, and slaughter them if they want to eat meat. Uh-oh, now my vision is blooming! This could be a model economic system--imagine every village, town, and city in the US of A run on this system of self-sufficiency. And then throw in regional trade and bartering, local economies and you'd have... happy people? Respectable economies? Much less exploitation? Strong communites? Arts and crafts that varied by region, reflecting a diversity of cultures?
Hey, sounds alright to me. Let's test it out on the criminals first, see how they do. Once they are rehabilitated, we'll create jobs for them--honorable ones--sending them out to different communites to teach food systems, trades, crafts, how to get along with your neighbor in a high-conflict situation, and general self-sufficiency and sanity. Now that's a prison system that I could support.
