Con: Disadvantages of Prison Privatization In response to arguments in defense of privatization, opponents counter that private prisons are not more cost-effective than public prisons, do not on the whole perform better than their public counterparts, and are actually less transparent and accountable.
Taxpayers spend $60 billion a year for prisons. In 2005, it cost an average of $23,876 a year to house a prisoner. It takes about $30,000 per year per person to provide drug rehabilitation treatment to inmates. By contrast, the cost of drug rehabilitation treatment outside of a prison costs about $8,000 per year per person.
