Confessions of an Economic Hit Man (ISBN 0-452-28708-1) is a book written by John Perkins and published in 2004. It tells the story of his career with consulting firm Chas. T. Main. Before employment with the firm, he interviewed for a job with the National Security Agency (NSA). Perkins claims that this interview effectively constituted an independent screening which led to his subsequent hiring by Einar Greve, a member of the firm (and alleged NSA liaison) to become a self-described "Economic Hit Man."
