That only works when buyers are willing to pay it. If oil companies have unilateral control over the price of oil, why isn't it already $300/barrel? And why was it ever $15/barrel, with oil companies going bankrupt?
Just because at one point in time the U.S. oil companies were not doing well, does not now mean they haven’t figured out they can get away with these unjustified price hikes. People in this country are highly dependent upon transportation in these times, whereas 30 years ago people didn’t need to travel nearly as much just to make a living. Families use to live closer to each other than they do today. Neighborhood markets were much different. Trying to compare the past with the present is apples and oranges.
