Did he say "costly to the American taxpayers?" Well, he can get away with that because he suspects you don't realize - and many Americans don't - that every penny of additional taxes these evil oil companies have to pay to the federal government will be added to the cost of the products they produce. The tax increases will show up at the gas pumps. I know that this is a difficult concept for the government-educated dumb masses to understand, but corporations - and this includes oil companies - don't pay taxes. They collect taxes from their customers, shareholders and employees and pass them on to the government.
Again ... let me point out that the greatest ally the looters in Washington could possibly have is an uneducated population.
