was explained in theoretical and statistical detail by Currie ("Mr. Inside") and by Harvard's Alvin Hansen ("Mr. Outside") in testimony before the Temporary National Economic Committee to highlight the role of government deficits in the recovery process. White House Named FDR's White House economist in July 1939, Currie advised on taxation, social security, and the speeding up of peacetime and wartime production plans. In January 1941, he was sent on a mission to China for discussions with Generalissimo Chiang Kai-shek and Chou En-lai, the Communist representative in the Chinese wartime capital of Chungking. On his return in March, he recommended that China be added to the lend-lease program. He was put in charge of its administration under the overall direction of FDR's special assistant Harry Hopkins. Currie was also assigned to expedite the American Volunteer Group (Flying Tigers), which consisted largely of U.S. military pilots released for combat on behalf of China against Japan and technically part of the Chinese Air Force under the command of Claire Chennault. Currie also organized a large training program in the United States for Chinese pilots. In May 1941, he presented a paper on Chinese aircraft requirements to General George C. Marshall and the Joint War Board. The document, accepted by the Board, stressed the role of an air force in China could play in defending Singapore, the Burma Road, and the Philippines against Japanese attack. It pointed to its potential for strategic bombing of targets in Japan itself. These activities, together with Currie's work in helping to tighten sanctions against Japan, are said to have played a part in provoking Japan's attack on Pearl Harbor. Currie returned to Chungking in July 1942 to try to patch up the strained relations between Chiang and General Joseph W. Stilwell, commander of U.S. forces in China. Currie was one of several of FDR's envoys who recommended Stilwell's recall and reassignment. Back in Washington, Roosevelt asked Currie to put his case to General Marshall, but the General dismissed the idea. Only much later did Marshall concede that his protégé's continued presence in China was indeed a mistake. Stilwell was recalled in October 1944. From 1943 to 1944, Currie served as Deputy Administrator for the Foreign Economic Administration where he played a major role in recruiting or recommending economists and others throughout the Washington administration. Prominent examples are John Kenneth Galbraith, Richard Gilbert, Adlai Stevenson, and William O'Dwyer.
