I equate it to the pecking order in a chicken coup. The hens figure out which is the weakest hen and begin to peck it to death, but, the farmer will not remove it. As soon as he does, the hens find a new weakling to peck on. So as long as there is a pecking order there will be a System Administrator.
The problem with the “pecking order”... is you always work for the “head pecker”
