There is no doubt that this guy would be good management material, considering that he knows how to get things done and knows how to be friendly with people in a manner that helps him out. But the point is: a lot of people who want to be in upper management are not willing to build their relationships with other people in the company based off a non-personal need. They want their friends to be real friends, and not just strategic short term allies.

I'm not picking a side here, I'm just pointing out the operating mode that has resulted (in my observation) in at least one person getting ahead pretty quick.
