Private prisons are a billion dollar industry here in the United States, but is that really something that should be left to private companies or should the government handle it? I heard a report on NPR on this topic and there are arguments about the practicality of private prisons on both sides: http://www.npr.org/2011/03/28/134855801/private-prison-promises-leave-texas-towns-in-trouble But, of course, they never stopped to ask whether or not that is a legitimate function of government or not. What do you think?
