I'm still digesting this article by David Brooks. Brooks argues that the battle within America's "aristocracy" is the source of much of the polarization in American politics.
Professionals vs Managers isn't exactly the Crips vs. the Bloods, but I do think Brooks has a point. I'm not sure that the Managers title can include the so-called "Christian right" that can often be found on one side of many of the polarizing debates.
