According to the National Institute of Justice, private prisons tend to make much lower estimates of their overhead costs to the state for oversight, inmate health care and staff background checks.
Officials at public prisons often argue that the state winds up paying a higher cost for those services than is advertised, mitigating savings that private prisons are built to deliver.
A study this year by the Arizona Department of Corrections found that when various costs are factored in, it can be more expensive to house an inmate in a private prison than it is to house one in a state-run prison.
The cost of housing a medium-security inmate is $3 to $8 more per day in a private prison, depending on what assumptions are made about overhead costs to the state, the study found.
Travis Pratt, a professor of criminology and criminal justice at Arizona State University, said there is no evidence that private prisons save government agencies money, even though they typically promise up-front savings.
To maintain profit margins, Pratt said, companies often cut back on staff training, wages and inmate services.
This is really important, y’all, even if you don’t live in Arizona, which I don’t. there’s really a lot to be said against privatising prisons. It feeds into the idea that prison is not a rehabilitation point for severely wayward souls, but instead essentially a place to store people that you do not want in the free world.
This is the wrong idea to be having about prisons.
