I believe we would have less than 20% of the crime we currently suffer from if we were to actually commit to rehabilitation. Instead we put every criminal, even minor offenders into a brutal gladiator environment where young men are sold into sexual slavery just to survive. Many come out after only a few years as violent offenders who hate everyone.
Our juvenile and foster care systems are just as bad.
Yep, prison is where the state has justifiably total control over a bad or troubled persons life and instead of doing every thing they can to grab them and try to change them for the good, or to reshape them or teach them, we make them worse.
