Any increase in taxes that the oil companies pay will be passed on directly to the consumer. They are doing us a favor by only charging 3.52 per gallon. Demand is inelastic for oil- they can charge ANY price they want, and they know it. The only reason crude is so expensive is because that's what they want it to be. Invest in these companies, because you won't find another company more profitable than these.
And if we start drilling in the states (ie S. dakota) and build more refinery's, I'm not entirely convinced that will do anything at all to the prices at the pumps, again, because demand is inelastic. Once we fix that little demand problem, things will start to change, but drastic changes will have to be made, not only in this country, but in the world.
Looking forward to purchasing an electric car in the next 3 years (ie chevy volt).
