I live in Wisconsin. When the Ethanol Mandate went into effect I caught a farmer on a call in show.
He was receiving $1.25 per bushel of corn. He had told his wife that it was their last year. He was giving up! The mandate announcement immediately jumped the price to over $4.00 per bushel! He no longer needed to quit. But that is not the price only for corn into ethanol, but corn in general. Meaning that everything that uses corn has an concomitant increase in cost and hence price to us.
