No question there is creativity outside of Belmont. What he seems to be suggesting, however, is that the folks of Belmont will want to send their kids to school in Fishtown so that they can experience the diversity of our culture. But even Obama sends his kids to an elite private school, so Murray is dreaming if he thinks that’s going to happen.
Actually I think what he is saying (from the whole article) is that everyone sent their kids to the local school sp you had a mixture of Belmont and Fishtown in the same building, and in the streets, and in civic organizations, etc.
I remember when I went to Catholic school many moons ago, and granted they were private diocesan schools, but not elitist ultra-expensive schools, we had kids whose parents never went to college (like me) and we had kids whose parents went to college and set up computer systems for entire countries. Even though we were overwhelmingly white, there was a real diversity of background there.
