From Howard Zinn’s A People’s History of the U.S. (Chapter 24: The Coming Revolt of the Guards):
History which keeps alive the memory of people’s resistance suggests new definitions of power. By traditional definitions, whoever possesses military strength, wealth, command of official ideology, cultural control, has power. Measured by these standards, popular rebellion never looks strong enough to survive.
However, the unexpected victories-even temporary ones-of insurgents show the vulnerability of the supposedly powerful. 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 communications workers, garbage men 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.
Certain new facts may, in our time, emerge so clearly as to lead to general withdrawal of loyalty from the system. The new conditions of technology, economics, and war, in the atomic age, make it less and less possible for the guards of the system-the intellectuals, the home owners, the taxpayers, the skilled workers, the professionals, the servants of government-to remain immune from the violence (physical and psychic) inflicted on the black, the poor, the criminal, the enemy overseas. The internationalization of the economy, the movement of refugees and illegal immigrants across borders, both make it more difficult for the people of the industrial countries to be oblivious to hunger and disease in the poor countries of the world.
