Some very confused posts in this thread...... Let me try to clear some of them up.
No, the gas stations are not the ones making the big bucks. In general, gas stations purchase the gas from a few major suppliers and have a very small profit margin. There is sufficient competition which has driven down the margins for gas station owners.
There is nothing wrong with a company making more $$, that's what a free market is supposed to be all about. However, when it comes to oil production and refining, the free market mechanisms that usually drive prices down fail because there isn't any true competition, and demand is very inelastic.
In what other industry do profits go through the roof when the cost of goods sold (for example, the price of raw materials) rises rapidly? None. The only way that is possible is if there is a very inelastic supply curve and a lack of competition. In theory, if there is competition, then the rising price of oil would simply be passed along to the consumer, or absorbed by the company (for example, Exxon). Profits would not increase as the cost of oil went up. Normally, in market with competition, rising costs of raw materials (in this case oil) would eat into profits, not increase them. As an example, take a look at the airline industry.
Clearly, currently profits for the big oil companies are going up roughly in a linnear way along with the price of oil. That means that not only are the companies passing along the increased cost of goods sold, they are increasing their margin at the same time at the expense of the public. Without competition, there is no incentive not to, and since oil is to a large extent a nesessity the consumer can't take action. Consumers can reduce consumption over the long term by conserving and driving more efficient vehicles, but not in the short term. Unless the oil companies can show that profits are rising as a result of efficiency or decreased expenses, one would have to conclude that they are gouging the public.
The federal government has now also started an official inquiry into price gouging by the oil companies.
