This paper discusses economic, social, and political trends and values/beliefs that will affect the quality of life of persons with developmental disabilities and their families to the year 2000. The paper describes four plausible future scenarios: "America Revitalized"; "Post-Industrial Reformation"; "The Stressed Society"; and "The Community-Welfare Society." An overview of current values in the field of developmental disabilities examines the degree of consensus about such values as independence, productivity, integration, normalization, and quality of life. The paper then delineates implications of each future scenario for persons with disabilities, including the relationship between what is currently seen as desirable (current values) and what may occur. A most probable future is then forecasted, and implications for organizations that serve persons with disabilities are presented in such areas as values, employment, integration, technology, quality of services, minorities, support services, housing, and education.
