Orden does believe that over the long term, there has been progress in abolishing some of the most wasteful farm subsidies. "We used to do all sorts of things to maintain high market prices for farmers," he says.
For example, the government used to buy up large amounts of agricultural commodities and either store them or export them at much lower prices. It also paid farmers to take vast amounts of land out of production. Those programs, Orden says, were probably more damaging to the overall economy than the payments and crop insurance payouts that farmers get today.
The U.S. Department of Agriculture (USDA) spends $25 billion or more a year on subsidies for farm businesses. The particular amount each year depends on the market prices of crops and other factors. Most agricultural subsidies go to farmers of a handful of major crops, including wheat, corn, soybeans, rice, and cotton. Roughly a million farmers and landowners receive federal subsidies, but the payments are heavily tilted toward the largest producers.
