It is simpler, but not for the reasons you describe. The issue is that once you have layers of middle managers - as in managers managing managers, a snake pit ensues. Nobody gets into middle management and says “ahh at last, I’ve arrived”. The goal is to amass influence and push up as quickly as possible to try and reach the executive level. From here, it becomes a very political situation, rife with corporate climbers try to push each other down into the mud to reach upward. One way to appear influential is to manage a large team of people. Your main goal is to pull headcount for your org chart, while your peers are also trying to do the same. So you invent ridiculous “strategies” with inflated headcount requirements and promise astronomical results. It all stems from the personal ambitions of the people in the middle. And of course, they’re usually the most out of touch with the real operations of the company because they’re only peripherally connected to any actual work as a distant connection in the telephone game.
