Why is it fair and how can it be possible that American economics control world economics?

America is the World’s number one consumer. America has the power to establish laws that mandate price controls (i.e., what its consumers pay for goods and services) thus affecting and controlling the World’s economy.

Furthermore, America can establish laws that protect the people of manufacturing countries from human rights abuse. America will not consume goods and services unless the country from which the goods and services originate support and protect the basic human rights of the people who create these consumer goods and services.
