The natural distribution of productivity and creativity follows what's known as the Pareto Distribution. In laymen's terms, the 80/20 rule. Vilfredo Pareto (1848 – 19 August 1923) showed that approximately 80% of the land in Italy was owned by 20% of the population. A more mathemative formulation of thzis natural law is Price’s Law, 50% of the work is done by the square root of the total number of people who participate in the work. It's also known as the Matthew effect from the Parable of Talents, in short, the rich get richer and the poor get poorer.
If you carry the principle/formula out--it doesn't stop at the 20/80, you end up with 1% owning most of the wealth.
It is a natural law. It applies to any area. It has nothing to do with greed. It's just the way things shake out.
