All large organisations have huge amounts of "useless" overhead. When this overhead is removed, you no longer have a large organisation. Sometimes, having a large organisation is worth the overhead: organisations quietly solve a great deal of issues. But, since they do this quietly, it can be hard to tell which issues they solve; and they loudly create a lot of issues, too. This means it can be hard to tell when they are or aren't worth it, and when organisational reform would actually be expected to improve things.
