"Less extreme leftists have been no less enthusiastic for war's potential to transform the home front, Nisbet added. Leftist intellectuals were practically unanimous in favoring U.S. entry into World War I since they understood the opportunity it presented for institutional change at home. Wartime economic planning, they were convinced, would help to erode Americans' conservative beliefs in the limits of government and the inviolability of private property. The experience of wartime planning never entirely faded from the national consciousness, and certainly not from that of the Left. When the Depression came, the Left jumped at the chance to revive the spirit of government planning it had so assiduously cultivated during the Great War. The rallying cry was "We planned in war"; now, therefore, we shall plan in peace. War symbolism was ubiquitous in the imagery adopted by Franklin Roosevelt's New Deal. "In terms of frequency of use of such symbols by the national government," wrote Nisbet, "not even Hitler's Germany outdid our propagandists."
