Rehabilitation has never really been the point of the US prison or even correctional system at all.
The fact you can serve your time, earnestly work on rehabilitating yourself, jump through all the hoops, etc. but still be under the economic death sentence more or less summarizes how people feel about it.
It’s basically NIMBY applied to the justice system. Everyone loves to pretend they want rehabilitation but also wants someone else to do it. This shows up in hiring, apartment leasing, social benefits, etc.
