Book excerpt: The author discusses the effects of two major social trends in American life on the role of Jewish center workers. These trends are: the socio-economic mobility of American Jewry, and the national trend of integration in education and housing. The author asserts that Jewish social agencies will need to reevaluate their roles and relationships to clients in order to keep pace with these new realities.
