This seems completely wrong to me. If you look at who is the top 0.1% it's either inherited wealth, a few professionals (lawyers, certain medical specialties, etc.) who own their own practices, or people who've managed large groups of people (i.e. business executives). The third group is overwhelmingly full of people with good social skills, and skilled professionals are almost always personable too.
For the banks and credit unions where customer service is a key advantage, operations people with good people skills are super important. But because of industry culture, these people are pretty much sh1t upon. It shows in their pay, and in the rapidity with which they are laid off.
I bet there's tons of places where this happens.
