So, our stupid obsession with trying to use our food for fuel is obviously causing pain for food producers and their employees. It is also resulting in a disproportionate amount of pain for this countries poorer people, for whom food is already a huge part of their budget. To make matters worse, ethanol does nothing to make our fuel cheaper or cleaner. Furthermore, when the fuel consumption, and related pollution, associated with full production cycle of ethanol is factored in, using ethanol for fuel may even have a negative environmental impact when compared to petroleum.
All of this pain, and who actually gains from this? Some farmers. Farmers who are growing grains for cash obviously like the higher prices. However, farmers who have to buy those grains to feed livestock are not exactly enjoying this. Mostly, the only people who gain here are companies like ADM and BP. The rest of us just suffer.
