The key to understanding the situation is summed up in a paragraph towards the end of the article. "Unlike some investments with only a few unknowns, ethanol has up to five price variables that affect plant profits: corn, ethanol, oil, natural gas, and transportation," Chavez writes. Since these five variables are constantly changing, anyone claiming to know what will happen in five years (including Chavez) is making a bold claim. Still, it's good to hear at least some dissent in the go-go ethanol boom seen 'round the country.
