The interesting question is: Why have movie stars and other celebrities become an aristocracy of secular demigods? It seems to me an objective fact that virtually any other group of professionals plucked at random from the Statistical Abstract of the United States — nuclear engineers, plumbers, grocers, etc. — are more likely to model decent moral behavior in their everyday lives. Indeed, it is a bizarre inconsistency in the cartoonishly liberal ideology of Hollywood that the only super-rich people in America reflexively assumed to be morally superior are people who pretend to be other people for a living.
I think part of the answer has to do with the receding of religion from public life. As a culture, we’ve elevated “authenticity” to a new form of moral authority. We look to our feelings for guidance. Actors, as a class, are feelings merchants. While they may indeed be “out of touch” with the rest of America from time to time, actors are adept at being in touch with their feelings. And for some unfathomably stupid reason, we now think that puts us beneath them.
