" The more highly competitive the market for labor and for the employer’s products, the higher the cost paid for discrimination and consequently the less leeway the employer has for indulging his prejudices without risking his own profits and ultimately the financial survival of the business. On the other hand, enterprises not subject to the full stress of a competitive market—monopolies, non-profit enterprises, government agencies—have greater leeway. "
