"King Corn" is in so many ways the story of how government food policy has entirely remade the food landscape in the United States over the last 40 years. From the massive expansion of the number of acres of corn grown across the country, to the ever-increasing ways that corn is incorporated into the food production process, to the industrial feedlots that produce most U.S. meat, "King Corn" illustrates how the food system is not only the product of corporate greed, but also of government policy that was intended to produce many of the results people see today. For students to understand this, to recognize that the history helps explain the current reality, seems especially important in an age when people face so many crises, from diabetes to climate change, that will require not just changes in personal lifestyle, but deliberate and focused policy from the government as well.
