The economist whose ideas provided a theoretical justification of the New Deal is John Maynard Keynes. To determine the correct answer, you can eliminate the other options that are not economists - Henry Morgenthau and Harold Ickes were politicians who played key roles in the New Deal administration, while Milton Friedman and Arthur Laffer are economists associated with different economic theories and policies.

John Maynard Keynes, on the other hand, was a British economist who developed the Keynesian economic theory, which influenced the economic policies of the New Deal in the 1930s. His ideas emphasized the importance of government intervention and spending to stimulate aggregate demand and combat recessions. The New Deal, under President Franklin D. Roosevelt, implemented many Keynesian-inspired programs and policies to tackle the Great Depression.
