The problem I have with most of the "project manager" bullshit is not related to hierarchy or structure. In my opinion, the role of a boss/leader is useful and most of the time necessary. But we're not talking about that, we're talking about middle-management, and this is a completely different story. Very often, managers don't have the legitimacy of a boss or leader, they're not charismatic or visionary, and they often are unable to do or even fully understand the job of those they are managing. Their role is mostly bureaucratic and to reduce slack.
