In a phenomenal episode of This American Life called Three Miles, producer Chana Joffe-Walt told the story of a “classroom exchange” that took place between two schools in The Bronx. University Heights High School is a public school; Fieldston is a private school. They are three miles apart, and for the University Heights students, visiting Fieldston and its sprawling campus was a shock. One girl was so overwhelmed by the disparity between her school and Fieldston, where tuition runs around $43,000, that she started crying.
