What was a key factor for the success of the New Deal Coalition after World War II?

The key factor for the success of the New Deal Coalition after World War II was the inclusion of labor unions in its support base. Labor unions provided a powerful and organized group of workers who were able to mobilize significant support for the coalition's policies and candidates. The post-war period saw a rise in union membership and activism, particularly among industrial workers, which helped to amplify the coalition's influence in elections and policy-making. Unions advocated for pro-labor legislation, social welfare policies, and economic reforms that aligned with the values of the New Deal, thereby solidifying a broad base of support across diverse demographics.

The inclusion of labor unions also represented a coalition that linked various economic and social groups, such as farmers, urban workers, and African Americans, in a common agenda. This coalition worked together to promote inclusive policies that aimed to address the needs of the working class.

In contrast, support from agricultural communities, while still relevant, was not as significant as the labor movement in galvanizing political power. Similarly, cutting taxes for the wealthy and eliminating federal programs would run contrary to the core principles of the New Deal, which aimed at economic recovery and support for the most vulnerable populations in society.
