Why are we paying $3 dollars a gallon for gas?

Stopped in for some gas today and couldn't believe how much it has gone up recently.  It seems it sneaks up on you a few cents a day.  I paid almost $2.94 for regular and it is not even Memorial Day yet.  You can bet that come this summer, it will be over 3 bucks again.  Why?  Is their a shortage  of oil?  Not that I know of. Are we going to see another round of record profits and revenue for Big Oil?  I guess so.  I read somewhere that a CEO of one of the oil companies actually made 400 million last year. How long are we going to take this?  It is ridiculous that we keep shelling out these monies so that a few big oil companies and some countries that despise and ridicule us can get rich off of our hard work (I don't mean just in the middle east either.  Our "friends" in Latin America are fermenting and financing unrest there on the oil money we give them).  We need a government that is going to stop paying lip service to getting us off the petroleum heroin and do something about it!
