To be quite honest, I see the same thing in my professional work. Everyone feels that their problems deserve more headcount. And heads make work, justifying more heads. Further, those heads want to get promoted, so they make-work to justify that too. And to compound the problem, people try to magnify their power and impact by becoming gatekeepers. More people to say no and more overhead and drag to every action.
It's unfortunately difficult to ask and to honestly answer why we do things and whether those things are worthwhile. It's even harder to take corrective action even if you admit that what you're doing is not worthwhile. I think it's one of the pillars of cost disease that is nibbling away the on-the-ground productivity of Western societies.
