Go here. Scroll down to "farmers' share of the food dollar, then further down to "bread". On average, the farmer gets 15 cents of a 4 dollar loaf price. Most goes to the grain processor and through them to the advertising and government lobbying. The subsidy industry is driven toward keeping farmers from costing processors very much, as well as keeping the focus on grains as a cheaptrade tool (easily transported and stored) for international government debts and coercion. Policy is almost never about health, especially health(insurance and drug profit)care.

Farmers will grow whatever the infrastructure is set up for, and they are the tail of policy now, because the money that wasn't spent on food (the Green Revolution) has been buying profits and policy (consumerism) other than what takes care of the land. The media and urban economists blame farmers for getting subsidies but those subsidies are crucial to the entire economy (feeding consumers cheap enough food and paying corporations to keep jobs in early voting states. There are about a million farmers left: compared to all of the people voting billions of times every day for "Always Low Prices" corporations.
