Frader's analysis moves between the everyday lives of ordinary working women and men and the actions of national policymakers, political parties, and political movements, including feminists, pro-natalists, and trade unionists. In the years following World War I, the many women and an increasing number of immigrant men in the labor force competed for employment and pay. Family policy was used not only to encourage reproduction but also to regulate wages and the size of the workforce. Policies to promote married women's and immigrants' departure from the labor force were more common when jobs were scarce, as they were during the Depression. Frader contends that gender and ethnicity exerted a powerful and unacknowledged influence on French social policy during the Depression era and for decades afterward.
