Everyone desires relationships and community. Most people want to belong to a cohesive, like-minded group. It staves off loneliness. It promotes identity. These are natural and very human instincts.
The people at the very top could fall by and grace you with their presence and give you a little largesse, and you'd be "Oh, I'm so beloved." In a way, it was kind of like flattery. The middle managers didn't quite have that cachet, but at the same time, they had to seem like they were of that caliber. So there's a little bit of loneliness at the heart of those with a little bit of power.
If someone were plucked from the group and given those responsibilities, they might find themselves growing more aloof, just by virtue of that promotion. Suddenly the group culture excludes you. I saw this in my own working life, and I don't think it's a coincidence - I sensed a kind of loneliness in middle managers especially.
