Except firefighters, prisoners, and society.
Everyone is better off.
Firefighters get additional support combating a huge problem, prisoners get shorter sentences, in society gets better fire prevention leading to fewer lives and Land Lost
Prisoners have to do dangerous work and suffer long term health consequences for no compensation. Reduced sentences don’t count because the base sentence can be set to whatever the state requires to meet slave labor demands.
Society loses because slave labor artificially reduces the cost of natural disasters. If slave labor is required to make an area safe for habitation then I submit that is not a safe place for habitation.
The ends do not justify the means.
At the end of the day, I dont think each of the things you said are true. I dont think there is wage competition, I dont think the state is setting sentences based on labor demands, and I dont think there is an impact to locations of habitation.
These two Wikipedia pages show examples of why I don’t think this practice is ethical.

However, I do agree that the moral hazards are too great around combining it with for-profit prisons and corporations.
I think the one area where I would find private employment acceptable is work release programs at market rate, provided the pay goes to the prisoners instead of the state. I think these programs should be expanded, and could help with child support, victim restitution, and stability upon release.
Taking the option away doesn't help anyone.
