Seven major turning points in the evolution of U.S. aging policy are identified and reviewed: (1) the Social Security Act (2) the Great Society (3) the federalization of Old Age Assistance (4) the enactment of comprehensive social services (5) Social Security improvements (6) New Federalism, and (7) medical cost-containment policies under Medicare and Medicaid. In the 1980s, significant and growing problems of uninsurance and underinsurance for health care have re-emerged. Simultaneously, state Medicaid programs are characterized by their increasing variation and inequities, while there has been a decline in access for the poor. The future of aging policy will be decided in the context of four socio-demographic realities: (1) population aging (2) trends in mortality and morbidity (3) the relationship between income and health, and (4) aging as a woman's issue. The article concludes with a call for a recommitment to the public interest and to public solutions which affirm that health care is an inalienable right.
