Actually, it is not our government that is causing the high prices as you implied, it is foreign governments.
If you remember, our oil companies were the ones who discovered, drilled, and built the infastructure for oil recovery in Saudi Arabia, Kuwait, Iraq, Nigeria, Oman, Iran, Venezuala, Libya, etc. etc. etc. and then once they were successful, these outlaw nations nationalized, ie stole the entire setup.
Plus, it would be rather difficult to fail to profit off the millions of the heaviest, fattest, low mileage gas hogs polluting our US highways, every other nation has much higher fuel efficency for its fleet, thereby making it more difficult to sell petro products to their consumers. If our fleets average fuel mileage were to double, the oil companies profits would be halved......
