Important in the devising and running of these programs were politicians and bureaucrats such as Henry Wallace, the Secretary of Agriculture; Milburn Lincoln Wilson, the first head of the Subsistence Homesteads Division, who was a social scientist and an agricultural expert; and Rexford G. Tugwell, a Columbia University economics professor who managed to be appointed the first head of the Resettlement Agency, despite refusing to present himself with a "homely, democratic manner" in his confirmation hearings. Tugwell understood that the status of tenant farmers would not change if they could not vote, so he campaigned against poll tax, which prevented them voting, since they could not afford to pay it. His agency's goals were the four "R's": "retirement of bad land, relocation of rural poor, resettlement of the unemployed in suburban communities, and rehabilitation of farm families."
