Book excerpt: Providing the breadth of a standard text and the depth of a contributed volume, Social Policy and Social Justice: Meeting the Challenges of a Diverse Society is built on a clear, conceptual social justice framework and provides up-to-date analyses of contemporary social policy issues, written by experts in their particular areas of research and practice. The book uses case studies and rigorous analysis to explore the relationship of social policy to economic, social, and culture transformation and the ongoing conflict between universal and population-specific conceptions of social welfare. The third edition addresses recent dramatic changes in social policy. It includes an assessment of policies adopted by the Obama administration, policy changes proposed and implemented by the Trump administration and Congress related to the country's social welfare system, and the effects of the Trump administration's immigration and criminal justice policies on communities of color. The #MeToo and Black Lives Matter movements, recent changes in the electoral landscape, and timely Supreme Court decisions are also addressed. Additionally, the text considers the future of Social Security and Medicare, employment policies, health and mental health policies, and more. Throughout, the text explores the impact of economic and social changes on conceptions of need and helping, the role of social policies and social services in promoting or preventing social and political change, and the ways in which cultural, racial, ethnic, gender, and religious identity affect the development and implementation of social policies. Social Policy and Social Justice is ideal for undergraduate and graduate social work courses, as well as classes in cognate fields such as nursing, public policy, and political science.
