Perhaps I'm wrong (I'll admit I haven't done my reading on this subject), but I thought the spike in gas prices over the last six years (during the fall of my senior of high school, I could buy a gallon of unleaded for less than a dollar) was almost entirely a result of OPEC's actions (OPEC is an oligopoly of sorts, right?) and restriction of refinery capacity.
