In a couple of posts last fall (here and here), I showed that corporations don't do much actual farming in the United States. True, agrichemical companies like Monsanto and Syngenta mint fortunes by selling seeds and chemicals to farmers, and grain processors like Archer Daniels Midland and Cargill reap billions from buying crops cheap and turning them into pricey stuff like livestock feed, sweetener, cooking oil, and ethanol. But the great bulk of US farms—enterprises that generally have razor-thin profit margins—are run by independent operators.
