Emphasis today is on the political and economic factors in social change in undeveloped countries. This approach, combined with the wholehearted acceptance of the role of the middle class as a psychological leavening agent in such countries, tends to obscure the presence of other factors. Especially are there other categories of human beings who are responding to the forces put into play by world changes and by the increasing pressures exerted upon the social systems of which they are a part. Recently, some of these groups have been given more notice, such as students, intellectuals, labor union members, etc. Another such important category is the servant class which for the most part has been ignored and yet which appears significant, even though not as a political group, in terms of both the effects it has on changes being attempted in social organizations and on the personality development of nationals in such countries.
