Article: Petroleum companies at the top of the Fortune 500

After reading some news reports yesterday regarding the Fortune 500 list that was just released, I decided to write an article for the Yahoo! Contributor Network on my take. There are some times when you read an about something and have an instant reaction. This is one of those times. I just found it interesting that three of the top ten companies were petroleum companies. In our economy, that just doesn't seem fair.
