LOL! I guess they are talking about folks who work as cogs in big corporate wheels. The CE probably isn't a PE. Nontheless I would think a CE would move up to a managerial position after 10 or so years and be making more like 70-80K. I have a cousin and an uncle who are architects and they make a LOT more money than the number they show, but they both have their own practices.
My starting salary out of college as a full-time electrical engineer 8 years ago in Texas was higher than all those listed in this article as average salaries today.
