Right now the punishment is confinement. When you add effectively unpaid labour in prison as part of acceptable punishment, you're also paving the way for a future where unpaid labor as a standalone punishment is also acceptable. That's just slavery by law.
Inside a prison, should they not have a similar responsibility? They commit a crime and as such are held in stasis? Should they not at least carry the burden of themselves
I don't think there's enough jobs in prisons that need physical labour where they can cover the costs. You would then have to train them in useful skills but incompetence is not a crime so you cannot penalize those who "cannot learn/do" skilled work.
Other alternative is to make them work the same job they did outside but that is a slippery slope with lot of potential for abuse.
Except for some rare cases, I think you'll find that the cost of keeping an inmate in prison for a day makes it that you never break even
At that point it really is just slavery, which they can already do as protected in the US Constitution.
(I’m not arguing for this. I agree with restitution and believe that sentences longer than a certain point are also pointless and a net negative to society.)
Hypothetically let's say govt is allowed to use unpaid labour outside menial tasks and the prison system is setup in a way to efficiently utilize the skills of their labour pool and is allowed to outsource their skills to private entities at attractive rate for covering prison costs (i.e. more money left for govt spending)
E.g. tradesmen employed on their related jobs. A programmer employed in software jobs or a technician "loaned" to a nearby lab etc.
Don't you think the local/state governments will then have incentive to fill their pool with "missing" talent according to the job requirements.
"The stated goal of the Swedish prison system is to create a safer society by reducing recidivism and rehabilitating offenders rather than focusing solely on punishment. This is achieved through humane treatment, education, and reintegration programs designed to prepare prisoners for life after release."
