The idea of students 'looking down' at (for example) the local plumber is often ridiculous, considering a plumbers' hourly rate often exceeds that of many lawyers.
As we all know, there is a frightening, decreasing correlation between college education and financial success. At the same time there are plenty of locals who work hard and pour money into real estate.
It's a disturbing truth for most college graduates who drink the kool-aid of "education equals financial superiority". And colleges are only too happy to serve up that kool aid.
eg: I know a guy my age who owns a dozen hardware stores. He made his first million before he was 30, and he dropped out of high school. He's also one of the sharpest business people I know.
Be nice to everyone. You might learn something.
