I personally think the high fuel prices are what caused the recession in the first place, used to be fuel was never above 2 bucks a gallon, instead by the time the dust settled I was paying over $4.70/gal for diesel. that was double my fuel budget and added another 500 bucks a month to my bills, just to operate my truck. the average family was likely seeing a 3-400 a month increase in fuel expense, people just don't have that much extra discretionary money laying around. add to that the inflation in other costs mainly food and its easy to see why soon after all that the home prices crashed and economy tanked.
I personally don't see fuel prices going up anymore, the economy will just flat out not support it. in my area I don't care what people are saying on the news but things are the worst they have been since the recession started. I look for fuel to rise slightly then enter a free fall, like they did after they topped out in price.
