For the record....... Buckley is dead and irrelevant to the current discussion
There is a sad, class-warfare undercurrent in articles like this one. Maybe it's because many people have never actually WORKED with an Ivy Leaguer, in which case the posters are as guilty of ignorance as the anti-capitalists et al who've never worked in the private sector.
I've had plenty of Ivy League-educated colleagues in my career. One of the brightest and most spot-on guys with whom I ever worked came out of Wharton (btw, Trump graduated from Wharton). Another guy was a management lecturer at Harvard. These guys worked like dogs AND could run circles around most other people.
I also know a massive share of non-Ivy's who were da bomb; they deploy learned lessons exceptionally well, and also work like dogs.
I also know stupid Ivy's and stupid non-Ivy's. It happens. Maybe one day I'll tally it all up and publish the confusion matrix. And maybe my experience differs because I'm in the private sector...your mileage may vary.
I don't doubt the zip code story from LS. I worked in Manhattan which is predominantly lib and this story from The Atlantic is excellent in this regard. However, Conservatives, as a rule, pride themselves on judging people as individuals, by their actions and character. It's what separates us from the mouth-breathing Antifa et al.
