In War, Work, and Want, Randall Hansen focuses on how the oil shock transformed not just the economy proper and the geopolitics of the Middle East region, but also the global circulation of people and capital for decades afterward. Hansen asks why, against all expectations, global migration tripled after 1970. Arguing that the OPEC oil crisis explains everything, he shows how war, migration, and the desire for ever cheaper products made by migrants led to a massive upsurge in global migration after 1973.
