The diversity inherent in human beings makes it more difficult for them to execute their jobs. Their jobs are easier for them when people conform to their rules. Bureaucrats hate diversity. Even if you don't want it or need it. Independent individuals are much harder to control than dependent people.
Bureaucrats like to feel in control of other people.
Bureaucrats believe that most people are like children, who need to be told what to do and punished for showing too much independence. Independent individuals set their own standards and details. They don't need the rules of the bureaucrats to lead productive and meaningful lives. Bureaucrats hate independence. They believe in giving orders to other bureaucrats.
