Demand increased supply remained same..that is the bottom line...US Feds, Big Oil cos this that are sub plots...basic economics still remains same....high prices are good in a way..huge guzzlers and oil addicts like the US must adjust lifestyle - either dig up more oil from Alaska and not worry about Polar bears or simply cut down consuming oil...build sub trains, buses, railroads and quit 3-4 cars per family and SUVs.
