The beneficent result followed inevitably from the action of wholly selfish motives--provided, of course, the democratic political system of equal rights was maintained in its integrity.

The fulfillment of the American Promise was considered inevitable because it was based upon a combination of self-interest and the natural goodness of human nature.

On the other hand, if the fulfillment of our national Promise can no longer be considered inevitable, if it must be considered as equivalent to a conscious national purpose instead of an inexorable national destiny, the implication necessarily is that the trust reposed in individual self-interest has been in some measure betrayed.

No preestablished harmony can then exist between the free and abundant satisfaction of private needs and the accomplishment of a morally and socially desirable result.

The Promise of American life is to be fulfilled--not merely by a maximum amount of economic freedom, but by a certain measure of discipline; not merely by the abundant satisfaction of individual desires, but by a large measure of individual subordination and self-denial.
