Before welfare reform, US states with more African-Americans were significantly less generous to their welfare recipients. My colleague Erzo Luttmer found that people in the United States who live around poor people of a different race are more likely to oppose welfare spending. There is a long historical literature, written by scholars like C. Vann Woodward, documenting the role that racial divisions have played in blunting the appeal of populist redistributors in the United States and elsewhere.
