Oil companies seem like the bad guys. There must be a conspiracy behind all of this. Why doesn't the government do something about this price situation?

 If there is a conspiracy, we can all participate. All of the oil companies are publicly held corporations. They have generally performed no better than, and in many cases worse that other sectors of the stock market. To participate in these perceived windfalls, one needs to call any stockbroker or visit an on line broker and make an investment in an oil company of their choice.
