With the world moving more and more in the direction of trade protectionism and war, it is worth remembering the origin of the fallacies upon which this movement is based.

What produces a man’s profit in the course of affairs within an unhampered market society is not his fellow citizen’s plight and distress, but the fact that he alleviates or entirely removes what causes his fellow citizen’s feeling of uneasiness. What hurts the sick is the plague, not the physician who treats the disease. The doctor’s gain is not an outcome of the epidemics, but of the aid he gives to those affected. The ultimate source of profits is always the foresight of future conditions. Those who succeeded better than others in anticipating future events and in adjusting their activities to the future state of the market, reap profits because they are in a position to satisfy the most urgent needs of the public.
