Why do you seem to believe that intelligence, being measured by Stanford Binet, is a innate quality of an individual?. I'm not trolling, this is a genuine question.
Most of the time, the best (in the "bright" sense) coworkers I had where educated in really expensive schools and went to good Universities.
Take the Flynn effect for example. Are more intelligent people being born today than a few years ago? Or we're better schooling people?
