(Can I just say for the record that having the person who wrote so eloquently on a different sort of tribalism--and this strikes me as similar, a sort of economic tribalism--agree with me on this is geeking me out just a little?)

Right. I'm now thinking of "Prep for Prep," which is a program for students of color in New York City, placing them in the expensive private/prep schools (like, ahem, mine). It's not just about the money (though that's a lot of it); it's also the support network and resources, and improving the economic diversity of the schools. Hell, by the standards of my school, I pretty much was the middle class. (Which says a lot.)
