If you can manage your own relationships then you don’t need nearly as many managers. That’s more money for you!

Sadly how many managers there are seems to have very little connection with how many are needed. If there are a lot of managers with nothing to do, they're not going to just disappear, and sadly the main way they can make themselves look busy is by wasting your time. (And I can't really blame them; I'd do the same in their place).
