Scientists Underpaid?

Why on earth are entertainers paid more than scientists?
Surely, if governments want to further technology and find out the intricacies of our past then there should be a larger monetary incentive?

if you took the average made by scientists and compared it to the average made by entertainers, i think it would be in favor of the scientists.
now, the question is, is the ammount more they make worth all the years working hard to get where they are in ocmparison to entertainers.
