Which historical macro practice effort was a response to the Great Depression?

The New Deal policies, including the establishment of Social Security, were specifically designed as a direct response to the severe economic hardships caused by the Great Depression in the 1930s. This period saw unprecedented levels of unemployment and poverty, and the New Deal aimed to provide both immediate relief to those suffering and long-term structural changes to prevent future crises.

Social Security, introduced as part of this initiative, established a safety net for elderly individuals and the unemployed, setting a precedent for government involvement in economic welfare. The New Deal encompassed a wide range of programs, from job creation projects to banking reforms, which fundamentally reshaped the role of the government in social and economic issues within American society.

While the other options reference important historical developments in social work and public policy, they do not directly represent the macro practice response specifically aimed at alleviating the suffering of the Great Depression. Reforms prior to World War I, Community Action Programs from the 1960s, and recent services for immigrants address different social issues and historical contexts, making them less relevant as a direct response to the economic conditions of the Great Depression compared to the New Deal policies.
