Jim Crow Democrats based their Cold War policy decisions on a white supremacist worldview. Their support for the reconstruction of Germany, the Marshall Plan, and strict displaced persons legislation was connected to the defense of the existing race and class system in the U.S. South. The danger of communist expansion and infiltration and the post-war process of decolonization posed a menace to traditional power structures, both at home and abroad. The southern economy relied on free markets to export their agricultural products such as cotton, on military spending, and on cheap labor. Race and class identity determined social status in the American South. Issues of race and labor were therefore intimately linked in the southern states, which made politicians from the area very apprehensive about the advancement of human rights, not only by the U.S. government, but also through the United Nations. Because human rights advocates promoted political and socioeconomic justice, white southerners considered their message a direct danger to established race and class relations in the region.
