Echo that. It's not just clevers (as the author has coined the word), but everyone wants to be with smarter people. Have u heard anyone say - I'll hang out with this good for nothing dude. This article is a joke.
Some people just want to be with attractive people. Or rich people. Or funny people. Or people of high social standing.
It's whatever their definition of "good for something" is... and that definition isn't always "smart".
