"While the usual suspects - Corrections Corporation of America (CCA) and GEO Group - operate prisons, numerous companies with similar track records provide services like health care, food provision and prisoner transport. Companies like Corizon, Aramark, JPay and GTL have histories of providing low-quality services, harming not only prisoners, but communities and taxpayers as well. We already know that the industry routinely cuts corners to make more profit, resulting in prison violence, lawsuits, accidental releases and high staff turnover."
