Google for "Vilfredo Pareto". Around the turn of the century, he
pointed out that the rich have most of the money -- quantitatively a
rough 80/20 rule. (I'm no statistician, but this clearly must be true
for anything that you can't have less than 0 of, and that has
substantial variance ... wealth, lifetime home runs, instruction
execution counts ... )
