Social security systems throughout the world are faced with unprecedented challenges in response to growing criticisms about unacceptable expenditures for government programs and questions about the appropriate role of government in providing social protection through social insurance and social assistance programs. The challenges are also a result of dramatic demographic, social, and cultural changes around the world. A variety of radical and modest reform measures are currently being discussed which have the potential of significantly impacting the means of income and health care for the elderly, children, and families. This book examines these challenges from the perspective of local analysts in both industrial and economically developing nations. The purpose of the analysis is to promote a better understanding of the integral role that social security plays in the social and economic development of diverse societies. The chapters examine the wide range of challenges to social security in Britain, Egypt and Turkey, the Netherlands, Poland, the United States, Uruguay, and Zimbabwe. An overview of the most prevalent issues are discussed, including fiscal viability, economic development, equity, administration, public confidence, and the role of social security as the primary government instrument for social protection against the loss of income and health. Essential reading for students and researchers in social policy, gerontology, and comparative social welfare.
