Are superstars payed more because...?

1. Their work is much more physically demanding than other professions?

Also:

1. Should superstars NOT make so much money because doctors, nurses etc. have jobs that save lives and make much less?

2. Should superstars NOT make so much money because all of the hefty fine money the players pay up (if they weren't rich, the wouldn't outburst so much because it would be costly to break out) could be used in AIDS in Africa?? Or other places' help programs??

EXPLAIN EACH ONE!!!!!!!!!!!!!!!

EXPLAIN THE BEST AND YOU WILL RECEIVE 10 POINTS!!!!!!!!!!!!!!! (also, i'm looking for at least 2 sources for each, explain your best)

Superstars make more money because people turn them into idols of worship. People pay for the tickets and buy all the peripherals such as tee shirts and hats. The money they make is based on revenue received by the promoters of the events. Most people really don't care about AIDS in Africa or anywhere else just as they don't really care about the homeless people living here that have to scour the dumpsters for food. Multi-billionaires could end poverty overnight but they just don't do anything except horde all their wealth. It's staggering to think that one billion is one thousand million and that people have more than one billion. Bill Gates is said to have 50 billion, Warren Buffet 40 billion. Just the two of then have 90 thousand million dollars and there are hundreds of other multi-billionaires. Why is there poverty in America? It's a sick world, literally!
