Also if it’s a decent company then you might have a job lined up for you once you’re out since you’ve worked there already and shown you can handle the job and so on. And having a job, income, some normalcy once you go out goes a long way. Turns this from exploitation to a way to reintroduce people to life outside of prison and whatnot. Not that companies wouldn’t benefit from this too, since it’d most likely be less money than a normal full-time worker, but it could be a rare win-win situation if handled correctly.
