"Cheap oil had allowed populations to explode in precisely those parts of the world that had had, for millennia, a high infant mortality rate and modest life expectancy. Cheap oil was behind the "" that increased the food supply in the nonindustrial world. Oil was also behind many of the medicines and preventives that had neutralized… diseases. Now, suddenly, most of those children… survived, grew up, and produced more children who survived and grew up, and over the course of the twentieth century, the global populations hurtled into extreme numerical overshoot. Populations were, in effect, eating oil, notably in [the form of] food exports from the United States, where agribusiness had completely taken over from agriculture. Local farmers in Africa, Asia, or South America couldn’t compete with corporate Archer Daniels Midland’s oil-and-gas-based grain crops and U.S. government subsidies. There was no point in even bringing their hardscrabble crops to market when sacks of cheap American wheat sat on the docks of Pusan or Colombo. Farmers in those places felt that they had no choice but to migrate to the city and find some other way to get by. The only comparative advantage that these people possessed was their willingness to work for next to nothing. Cheap oil and free-market globalism turned comparative advantage into a new kind of feudalism, with the corporations as the lords and the overabundant locals as the serfs. And then, when the comparative advantage of cheap labor… of one place, […] was superseded by the cheaper labor… of another place, […] the corporations just moved their operations."
