Sounds like you're pulling stuff from out of your ass, the truth here is corrective vs punitive, corrective leads to a lot less recidivism, unlike punitive. All you have to look at is recidivism rates in the US vs northern European countries that have corrective prison systems in place. Norway has a 20% recidivism rate compared to the US's 67.8% withing 3 years, and 76.6% within 5 years.
