Itβs not unreasonable to treat prisoners as a unique population / special case. They are not incarcerated so that they can continue gainful employment.
Prisoners should not be getting paid to cook, clean, do laundry, etc. to help operate the prison, for example.
My understanding was jobs that provided for options to work outside the prison (like cleaning up roadside garbage) were coveted chances to get outside and maybe earn some time off for community service.
Court ordered community service can also be a reasonable punishment instead of incarceration.
But if you dont like a moral argument, make it an economic one. Each prisoner in california costs like 100k a year: if you paid them reasonable salaries, and they reduce re-incarceration rates you will be saving orders of magnitude more money.
Forcing prisoners to pay for their incarceration creates the same incentives as slavery.
Why not?
Not being paid for things that you're otherwise also not paid for isn't a punishment, that's just normal every day life in general.
It would be reasonable to devote 10-20% of the wages to prison maintenance or victims reparations, but saying their labor is worth 1$ is preposterous.
