It appears that one of the consequences of privatizing prisons is that these private companies are renting out prison labor for a profit:

Sweatshop labor is back with a vengeance. It can be found across broad stretches of the American economy and around the world. Penitentiaries have become a niche market for such work. The privatization of prisons in recent years has meant the creation of a small army of workers too coerced and right-less to complain.

Prisoners, whose ranks increasingly consist of those for whom the legitimate economy has found no use, now make up a virtual brigade within the reserve army of the unemployed whose ranks have ballooned along with the U.S. incarceration rate. The Corrections Corporation of America and GEO, two prison privatizers, along with a third smaller operator, G4S (formerly Wackenhut), sell inmate labor at subminimum wages to Fortune 500 corporations like Chevron, Bank of America, AT&T, and IBM.

These companies can, in most states, lease factories in prisons or prisoners to work on the outside. All told, nearly a million prisoners are now making office furniture, working in call centers, fabricating body armor, taking hotel reservations, working in slaughterhouses, or manufacturing textiles, shoes, and clothing, while getting paid somewhere between 93 cents and $4.73 per day.

Seriously, our country is becoming something profoundly disturbing.
