The problem is far more fundamental. America operates under the premise that crime is a moral failing, and that reducing crime is mostly a matter of strong enough deterrents.

The underlying assumption that logically follows this thinking is that criminals are by choice beyond redemption (essentially enemies of society), and so your best course of action is separating them from the rest of the population. What happens after that is not your concern: out of sight, out of mind.

This mindset is readily apparent in the almost complete lack of societal reintegration services, and the casual use of isolation, despite the ample evidence of how much damage this does.
