Everyone of them.
Why do they deserve the millions of dollars they make? How many jobs do they provide to others? How much income do they actually bring into the local economy?*
Why are they not vilified for earning millions, perhaps hundreds of millions a year, and a CEO is? A CEO has responsibiliy for thousands of employees and the health of an organization. I could go on but why bother?
That said, some of them are good singers, good actors, good word smiths, etc. However, none should be chased by the media like they are. Who cares what they are doing right now? Twitter? What a waste of time.
Don't get me started on sports stars.
*Charlie Sheen ended up shutting down production of a very successful tv show. How many people were laid off due to his ego? And he was the most watched celebrity and we were told no one could act like him. No one can fill his shoes. And I should care? Why? I care only because people only spoke about Charlie and not the people who were out of work. Sad commentary on values.
