From what I'm reading increased fuel prices are directly linked to the reduction in interest rates and folks speculating in crude oil. We have some big oil people in government that are pulling in the profits in both fuel price increases and speculation.
Clark Howard, a noted econmist here in Georgia, noted that bringing interest rates back to Setember 2007 levels would drop fuel prices by $1.10 per gallon. I don't believe that demand has that much but instead there is a production reduction.
US crude oil production is stagnet and Saudi oil production has dropped by 400,000 barrels per day. Why pump more to get less $'s per barrel when you can pump less and get more. We need some leadership here and sadly it is not forthcoming.
