Punishment no longer constitutes a marginal area of the larger economy. Corporations producing all kinds of goods— from buildings to electronic devices and hygiene products— and providing all kinds of services—from meals to therapy and healthcare—are now directly involved in the punishment business. That is to say, companies that one would assume are far removed from the work of state punishment have developed major stakes in the perpetuation of a prison system whose historical obsolescence is therefore that much more difficult to recognize.
