This text investigates how unequal access to fundamental resources creates and maintains systemic social stratification. Jennifer Ball, drawing on her expertise in social work and sociology, provides a framework that categorizes inequality through the lens of essential needs such as housing, education, and safety. The book argues that inequality is not merely an abstract concept but a tangible force that operates across individual, organizational, and governmental structures.

Educators and practitioners frequently cite this text for its clear, practical organization and its specific focus on the needs of the helping professions. It is widely regarded as a foundational resource for students who require a structured approach to understanding systemic social barriers.
