Vox populi vox ignorati

Paul Krugman noticed this poll from 1938, in which most Americans got completely wrong what the U.S. needed to get out of the depression:

Do you think government spending should be increased to help get business out of its present slump? Gallup Poll, Mar, 1938

37% Yes

63% No

Of course, it was massive government spending from 1942 to 1945 that actually ended the Great Depression.
