Oct. 29, 1929, the New York Stock Exchange crashed, panic selling ensued and America plunged into the Great Depression. President Herbert Hoover, in a nationwide drive to aid the private relief agencies, stated: "Time and time again the American people have demonstrated a spiritual quality ... of generosity. ... This is the occasion when we must arouse that idealism. ... This civilization ... which we call American life, is builded and can alone survive upon the translation into individual action of that fundamental philosophy announced by the Savior 19 centuries ago. ... Modern society cannot survive with the defense of Cain, 'Am I my brother's keeper?'"
