The sad truth is, if that were the case, prisons would label what they do as prison labor and claim their wages or sell them connectivity and equipment at exorbitant prices. One upside is it would be a solid addition to their resume, but that’s after they find a company willing to hire ex-cons.

We would all be better off if prisons had rehabilitation and reintegration as their raison d'être, but with private prisons wanting to grow, I doubt that’ll happen any time soon.

somewhat related: in Russia, mobile phones are illegal in prisons, but somehow ends up available to some inmates. Sizeable amount of scam calls from "banks" etc are coming from there. Problem isn't solved for many years, of course prison management tolerates if not directly profits from that, but yeah: internet and mobile connectivity will be used for crimes, unless something else in how prisons work would change as well.
