Gas Prices

It appears gas prices will be at $7 by the end of the summer. That's a far cry from the .99c per gallon days which was only about five years ago. It bothers me that we can't find a cheaper way to make gasoline domestically wwithout relying on outside sources. I'd like to know who is profiting from this? I was listening to NPR on my way to work and was shocked to hear that petroleum companies only earn about .4cper dollar margin on the sale of gaoline. Find that vey hard to believe considering alot of upper management in most petroleum companies are walking away with enormous bonus packages and salaries.
