In recent years it has become commonplace to speak of the declining support for public schools as an unprecedented break in nearly 150 years of educational expansion. Acutally, public backing for the schools has waned and the educational enterprise itself has been called into question at various times in American history. The political controversies surrounding several of the nineteenth century challenges to the public schools have, in fact, been well researched. However, the politics of educational retrenchment in this century, particularly the struggles during the Great Depression, have received little attention. Such studies as Sol Cohen's Progressive and Urban School Reform and Julia Wrigley's Class Politics and Public Schools have described the retrenchment battles in New York City and Chicago respectively but merely as secondary events highlighting more significant trends. Cohen's study of the Public Education Association, for example, sees the budget battles of the early thirties as the last flurry of excitement before the decline of the organization. Wrigley uses her comprehensive discussion of Chicago's school crisis to illuminate the power of the newly emerging political machine. Unlike those studies, this paper will focus on the retrenchment controversies specifically as they influenced school policy and as they related to changes in educational politics in Detroit.
