There are all sorts of "smarts" and tremendous talents. Sometimes, I think, those who aren't degreed unnecessarily feel "lesser than," and sometimes those who are degreed falsely feel superior.
I think everybody who's finished, as we say, in his or her respective field, will acknowledge that some of the "best and brightest" weren't the ones who finished. Every grad program and law class has one of those. And some of the most brilliant, accomplished, erudite people I've ever known never finished high school.
And some of the multi-degreed folks I know are dumb. Great at what they do, obviously, but scary-dumb and every bit as dysfunctional as everybody else with really messy lives.
