Bechtel - a behemoth among closely held companies - has been the world's builder, benefiting from vast government contracts for engineering and infrastructure work in difficult places while it nurtured relationships with power brokers in Washington. In The Profiteers, journalist Sally Denton seeks to unravel the history of Bechtel. Her story is one of "how a dynastic line of rulers from the same American family conducts its business" and how its system of networking now pervades US capitalism. Anecdotes of Bohemian Grove, the secretive retreat that became an all-male "summer camp" for US corporate, political and military elites to toast marshmallows, skinny-dip in the river north of San Francisco and dress in drag for skits, elucidate the chummy nature of big business. As of 2014, [Bechtel's] reported revenue was $37bn, with projects and employees in 37 countries. The corporation's embrace of Saudi Arabia as a lucrative client and its decades-long and contorted experience in Iraq also makes sense of some aspects of US foreign policy - as well as its intelligence-gathering operations. The life and times of John McCone, a former Bechtel executive who later served as CIA director in the US administrations of Presidents Kennedy and Johnson, is chronicled deftly here. It is worth noting: McCone was and is critical to Bechtel's dominance today. He devised the idea of "cost-plus contracts" for the toughest jobs sought by government. Contractors are guaranteed a profit in such deals.
