Us Against Them: Ethnocentric Foundations of American Opinion is a book of social science research by Donald Kinder and Cindy Kam published by thhe University of Chicago Press in 2010. Us Against Them uses polling data to argue that white voters who identify as ethnic Americans strongly oppose those means-tested programs that they view as transferring wealth directly to members of racial and ethnic minority groups, including food stamps, welfare, and Temporary Assistance for Needy Families, but support programs they see as universal social-insurance, including Medicare and Social Security.
