Contrary to the belief that revolutionaries are disproportionately poor or down-and-out, "revolutionists are more or less a cross section of common humanity". While revolutionaries "behave in a way we should not expect such people to behave", this can be explained by the "revolutionary environment" rather than their background (p. 120). "'Untouchables' very rarely revolt", and successful slave revolutions, like Haiti's, are few in number (p. 250). Revolutionaries are "not unprosperous" but "feel restraint, cramp, ... rather than downright crushing oppression" (p. 250).
