What event marked the major historical turning point in the relationship between the government?

The major historical turning point in the relationship between the government and the populace in the United States was the Great Depression of the 1930s. The economic crisis led to widespread unemployment and suffering, prompting the government to take a more active role in the economy through New Deal programs. This shift established the precedent for federal intervention in economic and social matters, fundamentally changing how citizens viewed the government's responsibilities and its role in their lives. As a result, the relationship evolved toward greater expectations of support and regulation from the federal government.
