What happens when women know how much other women make
http://money.cnn.com/2017/09/12/pf/women-pay-transparency/index.html
In Japan, getting to know others' salary is considered to be impolite, and wage gap between empolyees in the same age is not preferred.
In many companies, it is rare to see wage gap between the empolyees who began to work at the same time and have worked for less than 3 years, even if their abilities are different each other.
So, if talented people know their wage, they will be disappointed.
