The film, by Mark Achbar, Jennifer Abbott and Joel Bakan, traces the birth of the corporation from the mid-19th century to the modern "bad apples" of Enron and Haliburton. It shows how the corporation emerged in law as a "legal person", imbued with a personality of pure self-interest, and how the rationale of "externalities" (which means the exploitative consequences on the rest of us of a transaction between corporations) cannot be deemed, according to Milton Friedman, to be legally anyone's fault.
