The closest I can come to agreeing with you is community service as a punishment or as a means to reduce one’s sentence. However, especially given what constitutes a crime is some of the bad states, and the evidence of coercion for working these jobs, it seems as those there is a perverse incentive to keep people working for little pay. At the very least, this work, if not something you have to volunteer for, should be assigned as part of the punishment from the court, deducting it against the other punishments levied against them: being in prison for xyz amount of time, or paying xyz fine, but this seems like it would need to be well regulated to avoid abuse.
