Final answer:
President Roosevelt's political philosophy can be summarized as a belief in the proactive role of government in the economy, to act as a steward and arbiter for justice between different economic forces, and to provide direct aid and reform measures benefiting the public.
Step-by-step explanation:
The crux of President Roosevelt's political philosophy was the belief that government should actively intervene in the economy to ensure justice and help the nation, especially during times of crisis like the Great Depression.
Roosevelt's approach was characterized by a willingness to employ various forms of federal assistance, including public works, social security, unemployment insurance, banking reform, and regulation of the economy to directly benefit the citizenry.
Roosevelt saw the presidency as a stewardship, a role in which he must act for the people's interest, even if it meant changing his mind frequently to address the nation's needs. He introduced several reform measures that leaned towards progressive ideals, thus expanding the federal government's role in individual lives and the nation's economic systems.
During his administration, Roosevelt also navigated the tension between national and state governments over public policy and funding. Despite initial opposition and legal challenges, public opinion eventually supported Roosevelt's broader governmental role, aligning with his view of government as the arbiter between various economic forces.
