In 1933, Franklin D. Roosevelt's Secretary of Commerce, Daniel Roper, appointed Flanders to the Business Advisory Council, which was created to provide input to the administration on matters affecting business. The Council then made Flanders chairman of the Committee on Unemployment. This committee recommended addressing the problem both geographically and by industry. Flanders reported, however, that when the committee made its recommendations President Roosevelt was preoccupied with augmenting the Supreme Court and ultimately chose the undistributed profits tax instead—a choice that Flanders felt discouraged capital investment.
