"In a highly developed society, the Establishment cannot survive without the obedience and loyalty of millions of people who are given small rewards to keep the system going: the soldiers and police, teachers and ministers, administrators and social workers, technicians and production workers, doctors, lawyers, nurses, transport and communication workers, garbagemen and firemen. These people -- the employed, the somewhat privileged -- are drawn into alliance with the elite. They become the guards of the system, buffers between the upper and lower classes. If they stop obeying, the system falls.

That will happen, I think, only when all of us who are slightly privileged and slightly uneasy begin to see that we are like the guards in the prison uprising at Attica -- expendable; that the Establishment, whatever rewards it gives us, will also, if necessary to maintain its control, kill us."
