Precisely. I would venture to guess that Zuckerberg doesn't look through the white pages for physicians that are self-educated college dropouts. I bet he also does not live in a building that was designed by a self-educated structural engineer, drive a car that was designed and built by a college dropout, or get his prescription medications from "Jimmy, the self-taught child pharmacist."
Our society is built upon the knowledge structure that we've built up. Someone who went to college would probably realize such things.
