It's not the ethanol that is making it so expensive, it's that it's in literally everything. All your meat is fattened with corn, your drinks and food sweetened with the syrup of corn, there is lecithin derived from corn stabilizing and thickening everything you eat. There are few things you eat that aren't biproducts of corn. Soy is in a lot of the things you eat too, so blame the government for paying corn producers to produce more and more corn at a loss.
