There are so many things wrong with the comments here that it's hard to know where to begin. First of all, it's America's enemies (Venezuela, Iran, terrorists in Nigeria, Saddam Hussein, etc.), China, India, and a growing human population that are responsible for the high price of oil.
Also, the Saudi people share in the oil wealth of that country. In 2001, when the price of oil was around $20/barrel they were on the verge of revolt. Their standard of living was very low so the Saudi royal family chose to drive up the price of oil rather than get overthrown. They did this with OPEC by limiting output. That was documented in newspaper for all you people with short memories.
Yes, 9/11 helped drive prices up, but it was many things that contributed to the rise including terrorism in Nigeria, the mullahs in Iran who use Hezbollah to cause trouble in the Middle East and cause uncertainty, OPEC cutting supply to drive up the price, the war in Iraq, Hugo Chavez's bluster in Venezuela and lack of American action to drill and add refineries for 30 odd years, our refusal to build nuclear reactors, and people like Ted Kennedy using their influence to keep wind turbines from disrupting his view on Martha's Vineyard.
You conspiracy theorists look like raving lunatics. Yes, that includes Bill Moyers. It's so easy for you leftists to simply blame George Bush, but the truth is much more complicated than your Bush Derangement Syndrome.
P.S. You might want to wipe that spittle from the corner of your mouth.
