Krazy Korrelations

Via Krugman, some pretty striking charts depicting the high correlation between wealth inequality and political polarization. Kind of makes intuitive sense, I suppose: when the national mood is one of "we're all in this together", you're going to see more sharing (redistribution of wealth) and more cooperation in Washington; and when the mood is more towards the "every interest group for itself" end, you see less redistribution of wealth and more rancor.
