I see it as business enabling this part of the rehabilitation.

I lived for years a few miles from a federal penitentiary, I had friends who worked inside. The picture I have is that prison jobs are good and sought after by the inmates. (Versus eternal boredom.)

It's better for the jobs to be meaningful than meaningless, as make-work projects would inevitably be. This is not a broken system, there are no credible politicians or officials calling for change.
