Earlier quoted context omitted.
Read the 13th Amendment to the US Constitution: "Neither slavery nor involuntary servitude, except as a punishment for crime whereof the party shall have been duly convicted, shall exist within the United States, or any place subject to their jurisdiction." The US penal system is explicitly a continuation of the former slave system. Slavery wasn't outlawed in the US, just made a monopoly franchise of the US governmen…
Not sure who's downvoting this because the comment is objectively correct [1][2][3]. The practice of "convict leasing" is modern day slavery. This system should be abolished or, at a minimum, the prisoners should be paid at least minimum wage so we don't have the state to pay to lock people up and then some private corporation to profit off slave labor.

Minimum wage is supposed to cover sustainable food, shelter, clothing and other basic physical needs (leaving aside the question whether it really does, it is the intent). The prisoner has these basic physical needs already taken care of. Therefore, it makes no sense to pay both prisoner and a free low-wage worker the same. Moreover, if it were the situation, the very next day every paper would have a headline "Workers are being paid prisoner wages - outrage!"
However, if the prisoners are allowed to work for commercial for-profit companies, the company that benefits from this work should be asked to cover a substantial part of the prisoner's sustenance bill - which also would be to the taxpayer's benefit. Of course, participation in such programs should be strictly voluntary - I imagine prison life is not too fun, so there should be a number of people who would agree to do it even for a relatively very low wage. That said, it could be incentivized e.g. by taking successful work experience into account for parole decisions, etc.
