>> You want to find a manager who thinks of himself as your equal rather than your slaver. > In my experience, this doesn't exist. ... Even if your manager tries to be an equal to you, they are in fact not your equal, they are your superior.

The key here is that the manager tries to be, influencing his behavior. Yes if you look at the org chart, their roles are different. Otherwise he'd have no authority to make decisions for the team. However, the quality described above isn't whether they are equal or not, it's how the manager thinks of himself.
