<p>Oscar Wilde once said “you can never be overdressed or overeducated.” </p>
<p>That being said, I think this is a correlation/causation issue. People aren’t developing poor social skills because they’re educating themselves. The individuals you’ve mentioned had no direction, so they went to grad school; it’s not as though they went to grad school and educated themselves out of direction and social skills. Nearly all schools have career centers that help with real world things like direction of study, internships, mock job interviews and career assessment tests. The students staying in school for comfort are not the students that go there to succeed. It isn’t the fault of “overeducation.”</p>
