Why are rich corporate executive demonized by Liberals, but very accepting of rich celebrities?

I see comments, read books, read articles, etc. from Liberals that paint CEOs and Execs of companies as greedy, money hungry, elitists. And hear complaints about the millions they earn, while their employees supposedely go hungry. However I also see Liberals rally to the support of many different Hollywood celebrities, as if its allright for them to be rich and elitist, such as Sean Penn, George Clooney, Jon Bon Jovi, but they also have employees who work for them who dont make much, while they make millions, and themselves are capitilists trying to earn as much as they can for movies. Why the double standard?
