Adam,
That explains why oil has increased, but not why gasoline has incresed as much as it has. I can understand prices in the $2/gallon range, but $2.70 is outrageous.
And since there is not a gasoline shortage, the supply and demand argument doesn't stand the stink test all that well. In short, they are able to meet and even exceed the demand with the current refining capacity. Neither does it explain the type of hike that took place yesterday IN THE COMMODITIES (futures) MARKET.
This is purely the result of FUD, speculation and greed. Not supply and demand. Not the increase in the cost of oil (which went up only slightly.) And most definitely not because of the local guy, who is only trying to make sure they have enough cash to pay the bills he is expecting later in the year.
Besides, I don't see anyone blaming the little guy. It all seems aimed at the big guys.
