Historians agree that Keynes influenced U.S. president Roosevelt's New Deal, but disagree as to what extent. Spending more than the government earned in taxes (called "deficit spending") was used in the New Deal from 1938. But the idea had been agreed to by President Herbert Hoover. Few senior economists in the U.S. agreed with Keynes in the 1930s. With time, however, his ideas became more widely accepted.
