The profit motive, speaking broadly, means a man's incentive to work in order to gain something for himself. In a rational society it is profoundly moral and thoroughly just. In a specialized business context, profit is defined as the difference between sales revenues and cost. It is payment earned by moral virtue, the virtue of a specific group within an economy, the prime movers. It is payment for the thought, the imitative ,the long range vision, the courage, the efficacy of business owners.
Profit is exploitation only in a mystic viewpoint of emotionalists.
