The longer lasting engine argument does not justify the outrageous waste and inefficiency involved in the fleecing of the American taxpayer. The ethanol subsidy is a scam that helps no one except the corn lobby and big refiners like ADM and Cargill. It's not simply a rip off because of fuel inefficiency it's a rip off because it takes far more energy to produce a gallon of ethanol from corn than it does from many other alternative sources. The added widespread damage from the meteoric rise in corn and other grains make it a fraud of the first magnitude. It's simply a case of runaway greed and self serving hypocrisy operating with the help of the US congress at the expense of the vast majority of citizens. It is an ongoing daily assault on our resources and the future of the country.
