I agree. This isn't a Jewish thing. All the elites you menion share this view. It is much, much wider than "Why Jews hate Palin". It is why the liberal elites hate Palin. Their hate is understandable in way. Consider what conservatives, myself included, often say of the Ivy League crowd:
The degrees they sweat blood to get a mean little. Better to have a tire store manager from Nebraska at Treasury than a Harvard Business school graduate. Most of psychology and all of sociology is junk science. Lawyers produce little of value and are often venal. The art the elites produce is crap. The Pulitizers, Oscars, Nobel and other prizes the elites give each other are risible. At best the liberal elites are worthless, at worst they are corrupt and evil.
I'm in CT. I see the parties, I see the gushing over achievements I don't consider achievements but merely punching a ticket to a high paying job society would be better off if it didn't exist. I know the sneers from the heartland hurt them. Not much defense to the charges either. All they can do is call the heartland stupid (cause we do not see how valuable the elites are).
