With many bearaucracies there’s plenty of practically valueless work going on.

Because some executive wants to brag about having over a hundred people under them. Because some proceas requires a sort of document be created that hasn’t been used in decades but no one has the time to validate what does or does not matter anymore. Because of a lot of little nonsense reasons where the path of least resistance is to keep plugging away. Because if you are 99 percent sure something is a waste of time and you optimize it, there’s a 1% chance you’ll catch hell for a mistake and almost no chance you get great recognition for the efficiency boost if it pans out.
