The True Believer: Thoughts on the Nature of Mass Movement is a good book for understanding the nature mass movements. Here’s a passage in which Hoffer suggests that the poorest members of the working class tend to avoid mass movements because they are too busy trying to make a living:
Discontent by itself does not invariably create a desire for change. Other factors have to be present before discontent turns into disaffection. One of these is a sense of power. Those who are awed by their surroundings do not think of change, no matter how miserable their condition. When our mode of life is so precarious as to make it patent that we cannot control the circumstances of our existence, we tend to stick to the proven and the familiar. We counteract a deep feeling of insecurity by making of our existence a fixed routine. We hereby acquire the illusion that we have tamed the unpredictable. Fisherfolk, nomads and farmers who have to contend with the willful elements, the creative worker who depends on inspiration, the savage awed by his surroundings—they all fear change. They face the world as they would an all-powerful jury. The abjectly poor, too, stand in awe of the world around them and are not hospitable to change. It is a dangerous life we live when hunger and cold are at our heels. There is thus a conservatism of the destitute as profound as the conservatism of the privileged, and the former is as much a factor in the perpetuation of a social order as the latter.On the kind of people who are the first to join mass movements:
The men who rush into undertakings of vast change usually feel they are in possession of some irresistible power. The generation that made the French Revolution had an extravagant conception of the omnipotence of man’s reason and the boundless range of his intelligence. Never, says de Tocqueville, had humanity been prouder of itself nor had it ever so much faith in its own omnipotence. And joined with this exaggerated self-confidence was a universal thirst for change which came unbidden to every mind. Lenin and the Bolsheviks who plunged recklessly into the chaos of the creation of a new world had blind faith in the omnipotence of Marxist doctrine. The Nazis had nothing as potent as that doctrine, but they had faith in an infallible leader and also faith in a new technique. For it is doubtful whether National Socialism would have made such rapid progress if it had not been for the electrifying conviction that the new techniques of blitzkrieg and propaganda made Germany irresistible.
