Exxon's profits are soaring with the recent oil price spike, but the energy industry's earnings aren't as outsized as the politicians seem to think. Thomson Financial calculates that profits from the oil and natural gas industry over the past year were 8.3% of investment, while the all-industry average is 7.8%. And this was a boom year for oil. An analysis by the Cato Institute's Jerry Taylor finds that between 1970 and 2003 (which includes peak and valley years for earnings) the oil and gas business was "less profitable than the rest of the U.S. economy." These are hardly robber barons.

This tiff over gas and oil taxes only highlights the intellectual policy confusion – or perhaps we should say cynicism – of our politicians. They want lower prices but don't want more production to increase supply. They want oil "independence" but they've declared off limits most of the big sources of domestic oil that could replace foreign imports. They want Americans to use less oil to reduce greenhouse gases but they protest higher oil prices that reduce demand. They want more oil company investment but they want to confiscate the profits from that investment. And these folks want to be President?
