Prices law
Price’s law states that the square root of the number of individuals in a population do half the work.
For example, you run a business with 100 employees. Price’s law states that 10 of those employees do half the work. As a more extreme example, if you have 10,000 employees, the law states that 100 do half the work. That is, 99% of the employees do as much work as the top 1%.
A large number of natural phenomena follow this law/distribution, e.g. size of cities, classical music plays, number of hockey/basketball goals scored, etc
