Of course it is. Are you blaming Wall Street or their government enablers?
Maybe you know some righteous companies that refuse to profit from government laws and regualtons?
Oh, I blame Wall St. for gaming the bio fuels credit market and government for creating the conditions that allow them to do so.
Refining companies that are required to purchase bio fuel credits deserve a level playing field in which to do so, not the loaded dice game the Wall St. sharks are operating.
