Franklin Roosevelt's New Deal has become a conservative force in American life. In saying this, I do not intent for a moment to dismiss the enduring significance of the social and political struggles of the Thirties. The old lassez-faire myths were decisively shattered, government recognized its duty to promote full employment, Social Security was accepted as a national principle, the mass-production workers created the CIO - and this is only the beginning of a list of accomplishments of those times. The welfare state which was begun then is manifestly imperfect and often unjust. Yet it took the United States a giant stride beyond the decade of Warren Harding, Calvin Coolidge, and Herbert Hoover. Still, the Rooseveltian program did not solve the central problem of the Depression: mass unemployment.
