I really don't think that IT workers are not satisfied because they are underrated. I think IT employees that got enginerering/CS degrees were expecting more exciting and innovative research and development kind of jobs and not to do some scripting using excel or some plain web data-base oriented systems. They are not underrated, they are overeducated.
