Historically, the educated elites used to support conservatives. Pretty much every revolution in history was against 'the elites', and some of these revolutions were justified. Polybius himself wrote for a very exploitative empire - so there's no need to support these elites uncritically. In modern America, there has been educational sorting where the Academy is pushing for its class interests, and using their own forms of vilification for that - reducing polarization would require a change there that is not going to happen.
