true, although I think it's worth pointing out that private prisons aren't as big a driver of mass incarceration in the US as a lot of people think. the privatization of services like food or health within public prisons, or replacing mail or in-person visitation w/ extortionate electronic systems, is probably much more significant.

similarly most exploitative prison labor doesn't take the form of producing goods for private companies (like the Whole Foods cheese thing) but consists of using inmates to reducing staffing & other costs inside the prison, like making them work in the kitchens or laundry

edit: immigration detention is the notable exception - about 70% of immigration detainees are held in private prisons, compared to about 10% of prison inmates
