I don’t think American prison labor qualifies as “jobs” since it doesn’t even pay close to minimum wage, which is a ridiculously low bar to begin with.
Do you mean to ask who pays their prisoners more for their labor?
I would happy to see the abolition of penal labor, but the widespread attempt to cast it as “slavery” feels hyperbolic - especially in comparison to the reality of chattel slavery.
Incarceration on the other hand is a different topic altogether and I think the US system is incredibly harmful and creates an environment that produces recidivism. The Nordic system of rehabilitation is far better.
