Among the great nations of the world today, only the United States of America champions the rights of the individual as against the state and organized pressure groups, and our faith has been dangerously weakened--watered down by a blind and essentially false and cruel sentimentalism. In "Social Classes" Sumner defined and emphasized the basically important role in our social and economic development played by "The Forgotten Man." The misappropriation of this title and its application to a character the exact opposite of the one for whom Sumner invented the phrase is, unfortunately, but typical of the perversion of words and phrases indulged in by our present-day "liberals" in their attempt to further their revolution by diverting the loyalties of individualists to collectivist theories and beliefs. How often have you said: "If only someone had the vision to see and the courage and ability to state the truth about these false theories which today are attracting our youth and confusing well-meaning people everywhere!" Well, here is the answer to your prayer--the everlasting truth upon the greatest of issues in social science stated for you by the master of them all in this field. If this edition calls this great work to the attention of any of you for the first time, that alone will amply justify its republication. To those of you who have read it before, we commend it anew as the most up-to-date and best discussion you can find anywhere of the most important questions of these critical days. --WILLIAM C. MULLENDORE Los Angeles, California November 15, 1951 WHAT SOCIAL CLASSES OWE TO EACH OTHER INTRODUCTION We are told every day that great social problems stand before us and demand a solution, and we are assailed by oracles, threats, and warnings in reference to those problems. There is a school of writers who are playing quite a _role_ as the heralds of the coming duty and the coming woe. They assume to speak for a large, but vague and undefined, constituency, who set the task, exact a fulfillment, and threaten punishment for default. The task or problem is not specifically defined. Part of the task which devolves on those who are subject to the duty is to define the problem. They are told only that something is the matter: that it behooves them to find out what it is, and how to correct it, and then to work out the cure. All this is more or less truculently set forth. After reading and listening to a great deal of this sort of assertion I find that the question forms itself with more and more distinctness in my mind: Who are those who assume to put hard questions to other people and to demand a solution of them? How did they acquire the right to demand that others should solve their world-problems for them? Who are they who are held to consider and solve all questions, and how did they fall under this duty?
