Many people are "spectators" when it comes to life.
They live vicariously through their movie and entertainment idols.
Another factor is being rich and famous has always been respected in America. Being a celebrity in America is the equivalent of royalty in other countries! They're "living the dream!" :)
Figuratively it's the difference between traveling first class and coach. Most people at one time or another have fantasized about having "superstar treatment" wherever they go and being adored.
