Part of the reason gas is so high in price is because it is also taxed like crazy....
Nothing will make the prices of gas go down.
You can try buying shares of an oil company, go to a share holder meeting, and purpose to lower the prices of a barrel. Do that and they will laugh their ass off and kick you out.

If we will pay 110$ per barrel right now, why would they lower the price to 60$ a barrel....
