Trading One Addiction for Another?

Ethanol may someday provide a significant proportion of our transportation fuels and help reduce the emissions of greenhouse gases that are warming the planet. Today the Chicago Tribune has a good editorial questioning the need for government subsidies for producing this fuel:

It is a good idea to encourage ethanol use, because it's a renewable resource that burns cleanly without the greenhouse gas problems of fossil fuel. Its expanded use could make us less dependent on oil from the ever-roiling Middle East. But if ethanol is going to be a significant, long-term fuel for this country, it's going to have to find its own place in the market. That won't come through a rigged system of subsidies and tariffs that protects domestic corn and sugar producers at the expense of American consumers….

Are we trading one addiction (oil) for another (government subsidies)?
