This answers a deep mystery that FallenPegsasus has commented on in the past:
Broad areas of peasant behavior are patterned in such fashion as to suggest that peasants view their social, economic, and natural universes-- their total environment-- as one in which all of the desired things in life such as land, wealth, health, friendship and love, manliness and honor, respect and status, power and influence, security and safety, exist in finite quantity and are always in short supply, as far as the peasant is concerned. Not only do these and all other "good things" exist in finite and limited quantities, but in addition there is no way directly within peasant power to increase the available quantities. It is as if the obvious fact of land shortage in a densely populated area applied to all other desired things: not enough to go around. "Good," like land, is seen as inherent in nature, there to be divided and re-divided, if necessary, but not to be augmented.Peasant Society and the Image of Limited Good, by George M. Foster.
Except in a special-- but extremely important-- way, a peasant sees his existence as determined and limited by the natural and social resources of his village and his immediate area. Consequently, there is a primary corollary to The Image of Limited Good: if "Good" exists in limited amounts which cannot be expanded, and if the system is closed, it follows that an individual or a family can improve a position only at the expense of others. Hence an apparent relative improvement in someone's position with respect to any "Good" is viewed as a threat to the entire community. Someone is being despoiled, whether he sees it or not. And since there is often uncertainty as to who is losing any significant improvement is perceived, not as a threat to an individual or a family alone, but as a threat to all individuals and families.
