"The Cross of Corn"
Tom Laskaway links to an enlightening CBO report on ethanol’s impact on food prices and carbon emissions which concludes that it makes food more expensive (boo!) while arguably increasing carbon emissions (also boo!) to say nothing of the direct budgetary costs of ethanol subsidies. His post asks “Is ethanol’s Congressional free ride coming to an end?”
I’m going to say no. The appeal of ethanol to the congress has nothing to do with issues about the merits of ethanol.
