> Many of the wealthiest billionaires dropped out of school, didn't even go, or didn't consider it important. There are also many wealthy via inheritance. So, looking at the wealthy is not the demographic cohort that reveals the value of higher education.
Yeah there is some serious selection bias there -- Bill Gates' dad was a wealthy lawyer who sent his kid to a private school that had it's own computer systems in the 70s; Jobs lived down the street from one of the founders of HP, etc.
