The for profit prison system would be an interesting series to write.
Atlantic Monthly
The idea of private prisons was greeted with enthusiasm ing the Reagan and Bush Administrations... The Clinton Administration, however, has done far more than its Republican predecessors to legitimize private prisons.
... The prison-industrial complex now includes some of the nation's largest architecture and construction firms, Wall Street investment banks that handle prison bond issues and invest in private prisons, plumbing-supply companies, food-service companies, healthcare companies, companies that sell everything from bullet-resistant security cameras to padded cells available in a 'vast color selection'.
