Profit and loss is the most effective feedback mechanism ever designed for those concerned with efficient use of resources. A pricing system free of government distortion is the most effective communication system devised by man, and is necessary for an effective feedback loop of profit and loss. This pricing system is language neutral, understood by all around the world.
State intervention distorts these systems. The state purposely acts to hinder communication that ensures the efficient use of resources. It distorts the systems that allow man to interact freely with fellow men everywhere around the world.
This interference divides man from man, whereas prices freely arrived at, and the subsequent profit and loss system, are designed to unite man.
Dividing man from man helps to generate the conflict that the state then uses as a tool to further aggrandize itself.
