Note the low wages, and most of these people shouldn't even be in prison. Drug related offenses, like being a pot head who never hurt anyone? Victimless stuff that is of no concern to the government? Charged for something that should be legal? A total prison strike is needed more than ever, but like maybe I should wake up. Ain't gonna happen.
I betcha the violent offenders that should be in prison aren't on the production line.
