A American had a good question:
Q: "... why we need so many administrators?"
A: Public schools rake in millions of local and federal tax dollars. It takes a lot of administrators to oversee the dispersal of those dollars. In fact, there's so much money involved, top administrators have to hire lower level administrators to oversee that dispersal AND, let's face facts, good administrators don't come cheap. You have to pay top dollar for qualified administrators. Of course, as you pay top dollar there are more administrators getting in line for those jobs. THEN you have to raise taxes, which means more money needs to be dispersed which means you need more administrators to oversee that dispersal.
