Doctors, nurses and teachers make a great contribution to society. It certainly is. But for some reason, for example, famous players get much more. I don't agree with that. It's unfair. Doctors, admit, often save someone's life. Teachers teach the same future doctors, so that they can then get a medical education. I would add Fireman to the list of the most important professions. They certainly save the lives of thousands of people!! And it is not clear why, those who know how to kick the ball, get more of those who save your lives...
