- Well, that's probably because the tree might fall on the house when there's a storm.

It has been hypothesized that artists and intellectuals tend to dislike markets because the measure of status in the market is income, and artists and intellectuals tend to do rather poorly on that measure, but they do well in terms of the currency "products of the mind". I like that theory because I find reductionism aesthetically appealing: Many phenomena explained by few first principles = Yummy!
If the status theory of artists and intellectuals' political preferences is right, it would explain this phenomenon by the same principle that also explains why you rarely hear a good word from a Pepsi spokesperson about Coke and why women say much nastier things about other reasonably attractive women's looks than men: They're badmouthing the competition. The same perspective also explains why women so wildly overestimate the attractiveness of their best friends: They're showing solidarity to their allies.
People. Once you start thinking about them, they seem pretty pathetic. I guess that's why they call social psychology The Dismal Science.
