Amid escalating anti-immigrant rhetoric ... private prison corporations are once again expanding their grip on U.S. detention policy. In fact, today roughly 90 percent of detained immigrants are held in privately operated facilities, the highest share in history. The industry is instead preparing for explosive growth. On recent earnings calls, CoreCivic executives announced plans to triple the number of beds in their facilities within a few months. That would mean an additional $1.5 billion in revenue for the corporation, more than doubling its annual earnings. Meanwhile, growing scrutiny of immigration detention practices has led to reports of abuse, medical neglect, and deaths in custody. Privatization, with the cost-cutting practices that define it, is the structural driver of human rights violations at these facilities. Private prisons corporations are just one piece of the sprawling prison industry. The U.S. carceral system is comprised of a vast and deeply entrenched network of public-private partnerships that make billions from incarceration and detention. Commissary corporations mark-up basic hygiene items like toothpaste or tampons by 300 percent or more. Private healthcare providers routinely deny or delay treatment, contributing to suffering and preventable deaths behind bars. Private food vendors serve meals that are frequently expired or nutritionally inadequate, all in the name of cutting costs and maximizing returns.
