How do distributions of income and wealth reveal the way power is distributed in a society?

Distributions of income and wealth reveal how power is distributed in society because usually those in the top income bracket control society in all its aspects including banks and other financial institutions, news media politics so that the rich people control society such as in our western capitalist countries despite the facade of democracy. In a socialist society on the other hand, money is distributed equitably amongst the vast majority of the people to meet their basic needs for health and medicine, education, food and clothing and shelter first and foremost.
