Prison is not a free market and is not subject to market efficiencies. The purpose is to extract the maximum possible value from human suffering. They do this by charging them obscene prices for every basic necessity, double charging the government for their needs, renting them out as slave labor (mandatory work at wages of a couple of dollars per day), and then lobbying fiercely to keep their position. The private prisons want it to be more costly, beacuse they have monopoly contracts and guaranteed sales.
