Of course he's going to say that. Why do you suppose that is?
And what do you think happens when we burn up our food supply? That's right, it makes all our food much more expensive. It's a tax you don't even see. Oh, but that's only agricultural products! Think again, what do you suppose they feed livestock with, big macs?
I was in the commodities market when ethanol came out. I studied it even though I only invested in fuel once. I realized it was nothing but a money grabbing deal for the wealthy while screwing over the consumer. I mostly traded contracts on agriculture and meat products which is why I looked into it so intensely.
I trust independent research over a guy who is making tens of millions on a product he's pushing.
