If I were in charge, I would end farm and ethanol production subsidies in the US. They upset the price of goods the world over. It's not a big deal in the US, where we tend to spend little of our income on food. (If the price of a loaf of bread goes up a nickel, we can probably handle it.) But if you live in a poor part of the world, even a small increase in the price of rice, corn, or wheat may mean the difference between life and death.
