From The Wall Street Journal, January 27, 2007: “Ethanol gets a 51-cent a gallon domestic subsidy, and there’s another 54-cent a gallon tariff applied at the border against imported ethanol. Without those subsidies, hardly anyone would make the stuff, much less buy it — despite recent high oil prices.”
Remove this subsidy and the tariff. Remove the subsidy paid to farmers who grow the corn that is used to make ethanol. Then, the free market will rapidly tell us the true value of ethanol.
