Weak dollar caused oil's rise, OPEC president says
I've had to post this a few times, so here. OPEC isn't as sinister as people think, nor are the big oil companies. Mail a complaint to the Federal Reserve, specifically to Ben Bernanke. Oh wait, you would get a return to sender with a note saying "send to Secretary of Treasury" for questions about the dollar.
And yes, growing demand globally does put pressure on supply, increasing the cost. But it's not the main culprit. I guess people need to also take into consideration of how little refineries there are in the ME, and how they have to send the oil to Europe to get it refined, which also makes oil more expensive.
