^Why Movie Stars and Musicians get paid so much

   Movie stars and musicians help build society - its likes,
   dislikes, prejudices. They also provide a damper effect on a
   large amount of people, which prevents them from being
   dissatisfied with existence itself. This prevents civil war,
   promotes peace.

   So in that sense, movie stars and musicians serve a valuable
   purpose.

   That being said, their individual usefulness runs out quickly
   and they must constantly be replaced.^
