The principal effects of state economic control are familiar…they politicize life and provoke tension. They restrict the movement of people, ideas, commodities and financial resources. They curtail the volume and diversity of external contacts, and inhibit productive capital formation and obstruct both economic change and the effective deployment of human, financial and physical resources. They divorce economic activity from consumer demand…Their operation confers monopolistic or windfall profits and benefits on some people and inflicts losses on others…
