Well, if they're going to make alcohol out of corn, bottle and bond it and keep it out of fuel tanks.
They provide the product.
As others have declared, they can sell it to feed lots and bring down the price of beef and dairy.
The ethanol industry could blow up on a Friday and Monday morning, the commodity will be sold be a different industry.
But the entrepreneurs and other risk takers that were involved in the 'startup' turning corn into fuel....it's THOSE and all the tens of thousands of men and women paying mortgages, etc.. Right down the Indian behind the bullet proof glass at the pump.
