Zuck went to Philips Exeter. Boarding in 2011, that's $40,000 a year his dad shelled out for high school; non-boarding, still $31,000. OK, it wasn't today's dollars, but aying he wasn't "exactly poor" is an understatement.

Going to school somewhere like that is one of the experiences that develops precisely the attitude the blogger is talking about.
