Really, it's the fault of the movie studios combined with the populace. The sad truth is that a big name actor doesn't make a movie better, but it adds a big boost to how many people the movie can draw in. That's the real reason for the Emmys and Grammys and all the other awards being broadcast (seriously, how many other industries give out awards to successful employees/members? Tons, but they don't make them into big events). They help build up an actor's name so the studios get bigger boosts from using them.  Throw in the tribal mentality of worshiping a leader. It seems to be ingrained into people to rally to a star, whether sports, movies, politics, or local feuds. Now you can cheer on your figurehead versus their figurehead.  My conclusion, after my long rambling, is that the celebrities aren't going away. They are too useful to the top, who use them to sway or manipulate the masses, and they are too desired by the bottom.
