Why are Hollywood celebs usually super liberal when they are the biggest beneficiaries of capitalism?

they are out of touch with reality, they also do alot of things for show, like carmen diaz with her Toyota prius that she takes with her to press events and loves to talk about, she fails to mention she has at least 5 other cars all gas guzzlers like her sl63 AMG. they love to jump on the bandwagon. there say/do alot of stuff for the press in reality they spend/play hard and live it up who won't with if they had that kind of money. its easy to be a bigot when you have no worries and go on with your life as you wish.
