That's never worked in any place or time, so what makes you think it would work here and now?
By far the best results today come from a prison system that's so relaxed it startles even me. The Norwegian model. Norwegian prisons are roughly on a par with a decent long stay hotel and prisoners have, deliberately and explicitly, the full rights of citizens in all things apart from freedom. Towards the end of a sentence, they get more and more of that too. For example, one reporter doing a piece on the Norwegian model was met in town by a guide from the prison, who showed them to and around the prison. They found out that their guide was a prisoner, convicted of murder. Who had a pass to pop into town to meet the reporter and show them round. It was part of the "getting long term prisoners used to freedom" thing.
Norway serves as a good comparison of systems because until ~50 years ago it had a punitive penal system. A real doozy. Loads of people imprisoned, forced labour and all that sort of thing. Under that system, the recidivism rate was 90%. Then they radically changed their criminal justice system to a rehabilitive system. Most criminals not jailed at all, short jail sentences (21 years maximum, usually much less), pleasant jails, etc. And, crucially, massive (and massively expensive) rehabilitation programs. The recidivism rate is now 20% and that's despite the fact that a third of prisoners in Norwegian jails aren't Norwegian. The recidivism rate amongst Norwegian prisoners is even lower. They also have hardly any prisoners - there's only about 4,000 people in jail in Norway and some of them are in what we wouldn't even consider a prison. Even the closed prisons in Norway, which more resemble a prison, are so much unlike traditional prisons that, for example, the prisoners have a union rep.
