Final answer:
The Roosevelt administration valued a strong labor movement as a means to maintain unity within the nation, which was believed to contribute to economic stability and improved management-labor relations. It was a continuation of the trend wherein business leaders recognized the advantages of labor compromise, which included economic benefits like the eight-hour workday. Government intervention during World Wars also illustrated the effectiveness of planning and supporting workers.
Step-by-step explanation:
The Roosevelt administration believed that a strong labor movement would help maintain unity. This was anchored in the understanding that organized labor could promote stability and foster better relations between labor and management. During the Progressive Era and Franklin D. Roosevelt's tenure, significant strides were made to support unions and worker's rights, which translated into a more harmonious society with higher economic standards.
Corporate growth, despite government regulations like the Interstate Commerce Act and the Sherman Anti-Trust Act, did not hinder leading businessmen from acknowledging that a compromise with the labor movement could be advantageous. They hoped to prevent the spread of labor unions and maintain efficiency and output through voluntary reform. The importance of a united labor force was also emphasized by the government intervention during World War II, where business leaders and the government recognized the value in worker's demands, which led to the creation of benefits like the eight-hour workday.
In addition, the precedence set by the War Industries Board during World War I suggested that government planning could successfully stimulate the economy. This laid the foundation for policies during Roosevelt's administration focused on helping workers as a group through mechanisms like public works projects, which provided employment and revitalized certain industries.
