Final answer:
Ex-President Herbert Hoover believed that the national debt from the New Deal posed a serious danger to the country's future, consistent with his beliefs in limited government intervention and the potential harms of deficit spending.
Step-by-step explanation:
According to ex-President Hoover, the statement 'the growing national debt represented a serious danger to the nation's future' is TRUE. Herbert Hoover criticized the New Deal based on his belief that too much government intervention in business and the policy of deficit spending were detrimental to the United States. Hoover's presidency was marked by his adherence to a philosophy of rugged individualism and limited government intervention, and although he was not completely inactive during the Great Depression, his responses were generally seen as too little and too late.
Hoover disagreed with the New Deal because he believed it involved too much government interference and was afraid that the resulting national debt was a threat to the country's future. This notion is reflective of conservative criticisms of Roosevelt's New Deal policies. Hoover maintained this position, emphasizing the dangers of an expanding national debt and remaining consistent with his classical liberal economic viewpoints.
