California provides a glimpse of where this is all headed. For its firefighting, the state relies on upwards of 4,500 prison inmates, who are paid a dollar an hour when they’re on the fire line, putting their lives at risk battling wildfires, and about two bucks a day when they’re back at camp. By some estimates, California saves about a billion dollars a year through this program—a snapshot of what happens when you mix austerity politics with mass incarceration and climate change.
