On Heart of Darkness and Moby-Dick as examples of salvage capitalism:
Moby-Dick tells of a ship of whalers whose rowdy cosmopolitanism contrasts sharply with our stereotypes of factory discipline; yet the oil they obtain from killing whales around the world enters a U.S.-based capitalist supply chain. Strangely, all the harpooners on the Pequod are unassimilated indigenous people from Asia, Africa, America, and the Pacific. The ship is unable to kill a single whale without the expertise of people who are completely untrained in U.S. industrial discipline. But the products of this work must eventually be translated into capitalist value forms; the ship sails only because of capitalist financing. The conversion of indigenous knowledge into capitalist returns is salvage accumulation. So too is the conversion of whale life into investments.
