The Inconvenient Truth About Cheap Food and Obesity: It's Not Farm Subsidies

Pop quiz: What mistaken belief about food is endorsed by both the libertarian right and the foodie left?

Answer: That farm subsidies make unhealthy foods artificially cheap.

This myth gained currency thanks to Michael Pollan’s runaway 2006 bestseller, The Omnivore’s Dilemma, which blamed America’s bad eating habits on corn and soy, made cheap and ubiquitous by farm subsidies. More recently, the Cato Institute, and even George Will, have made the same claim.

Any complaint that food prices are too low might seem bizarre today, since world grain prices hit their highest levels in 30 years in 2008 and are now back up again. Yet this did not stop columnist Mark Bittman from reminding his New York Times readers that the price we pay for corn, soy, chicken, pork, beef, and high-fructose corn syrup is “unjustifiably low” because of farm subsidies.

Nothing could be farther from the truth. Our federal farm programs are designed to supplement the income of farmers, not subsidize the production of food. Most federal farm support programs either give cash to farmers whether they grow more crops or not, or boost farm income by raising crop prices through import restrictions, market controls, or temporary land set-asides, all of which make food artificially expensive, not artificially cheap.

For example, the federal sugar program uses a “tariff rate quota” to restrict the entry of less expensive foreign sugar into the United States market, which drives up the consumer price of all sweeteners, including high-fructose corn syrup. If our sugar program were eliminated, the price for most sweeteners would fall by 15 percent. We also place tariff rate quotas on imports of less expensive beef from South America. Our dairy program, in addition to import tariffs, employs “marketing orders” to prevent low-cost Midwest milk from gaining market share in high-cost regions such as the Northeast, making dairy products artificially expensive, not artificially cheap. Our Conservation Reserve Program takes farmland out of production in Kansas, driving up the price of wheat.

As for the corn program, it does provide “loan deficiency payments” that encourage a small quantity of extra production when market prices are low (which they are not at present). How much extra production? In an average year, American farmers produce about 4 percent more corn due to these incentive payments, lowering the price of corn slightly. This small effect is more than offset, however,  by the federal ethanol program, which now uses mandates, tax credits, and trade restrictions to shift nearly one third of all the corn we produce into “biofuel” use, to power automobiles. This ethanol program not only makes corn for food and feed much more expensive; it also diverts land away from soybean production, driving up the price of soy. 

So federal farm subsidy programs are not the cause of our obesity crisis. There is no denying that obesity-inducing foods are now cheap relative to consumer income in the United States, but this is not due to farm subsidies.
