Now lets say that being a brain surgion was the highest paying skill in the world, and suddenly every bright young person decided that he/she went to med school and specialized in brain surgery. Well not just everyone needs a brain surgion every day, so the pay rates for brain surgions would become very low. The brain surgery qualification may become less neccesary in our society that some skill at mopping floors. So would that mean that brain surgions somehow stopped contributing to society as much as they used to? Of course not. Compensation simply has little to do with human value.
