The 80:20 rule

 2021/4/1.  The 80:20 rule


I wonder that how many times I have wrote this theme.


80:20 rule

This is unfair rule which is called as “Pareto principle”.

https://en.wikipedia.org/wiki/Pareto_principle


If this rule is applied to whole people on the earth, what happens?


Certain people(20%) can use 80% of the earth’s assets, and almost people(80%) can use 20% of them.


The number of whole people on the earth is 7.9 billion.

20% of 7.9billion is about 1.6billion.

How big is the 1.6 billion people?

Almost as same as the number of Chinese.


China vs USA is simple.

Which is the king?
