Law of Competative Polarity
In a scenario where possession of a resource enables one to better attain that resource the distribution of that resource in the population will tend toward absolute polarization with one individual possessing all of it or several each possessing equal amounts and the rest possessing none. An example of this is money earning interest or power facilitating the accumulation of more power. This accounts for the recurring pattern in history of wealth becoming progressively less evenly distributed (until a revolution occurs).
This law is a specific instantiation of the more general phenomenon of positive feedback loops which occur everywhere in nature, e.g. in the immune system, in the weather, in evolution, and probably in the way human cognition functions (see link to the book On Intelligence on the contact page)
