Private Prisons Are a Failed Experiment
The U.S. has stumbled on a particularly inefficient form of providing services. Instead of having government employees do the work, or leaving it to the private sector, the U.S. sometimes combines government funding with private execution. This sort of pseudo-privatization generally fails to control costs, even as it reduces oversight and provides low-quality service.
There are many examples of this. No-bid contracting in the health-care, defense and infrastructure industries drives up costs. Expensive mercenary contractors like Blackwater (now Academi) were notorious for human-rights abuses during the Iraq War.
But perhaps the most egregious example is private prisons. Implementing criminal justice is one of the most critical, central functions of a state. Prison privatization turns this function over to contractors with comparatively little accountability. That opens the door for both cost overruns and mistreating inmates.
