The collection of essays, covering a wide variety of social welfare issues, attempts to develop a concept of a "new working class" composed of the poor and the underprivileged. It is asserted that such a class has potentially important contributions to make to society; further, social policy must be redesigned to meet its needs, rather than reflect the values of the middle class. A central proposal is that widespread use of nonprofessionals from the new working class should fulfill a unique role of their own in education, mental health, and all forms of social work. Although demonstrating a balanced view of situations and a creative capacity to invent new ideas, the authors are criticized in part for the type of support given to their recommendations. The reviewer emphasizes, however, that the weaknesses of the book do not lie in its substantive contents. 8 pp.
