What work fields pay the most money?

Medical Doctor while a prestigous field to go in too, because of the insurance fees make a lot less than people think. Illinois is the worst state in the union for medical doctors too.
The most money :Lawyers and CEO's. Look at our presidential runner up John Edwards, made millions of dollars defending insurance companies. Look at that CEO from Home Depot that just retitred, got over 100 mil when he got fired from his position at Home Depot because he could not do his job right.

Medical Doctor is certainly one of the highest earning jobs that a person can aspire to (without requiring a lot of luck like becoming an actor, singer, model, etc).
