"There are many reasons why capitalist society does not command the assent of the masses. There is to begin with the sense of injustice arising from gross inequalities. This is a fertile source of discontent and will always render capitalist society unstable. But I do not consider this by itself as fatal to the existing order. There have been inequalities throughout the history of mankind, but they have not always proved incompatible with a certain degree of social stability. Complete equality is a motive that has never moved large masses for any decisive length of time. It has inspired sects and special Orders but it does not appear to be a condition congenial to normal living. There are probably causes deep in the human psyche to explain this, but they lie outside the province of this book. A sense of injustice does not derive solely from the existence of inequality. It arises from the belief that the inequality is capricious, unsanctioned by usage and, most important of all, senseless."
