An early guaranteed minimum income program in the U.S. was the Aid to Families with Dependent Children (AFDC), established by the Social Security Act. Where previously the responsibility to assist needy children lay in the hands of the states, AFDC transferred that authority to the federal government. Over time, the AFDC was often criticized for creating disincentives to work, leading to many arguing for its replacement. In the 1970s, President Richard M. Nixon proposed the Family Assistance Program (FAP), which would replace the AFDC. FAP was intended to fix many of the problems of the AFDC, particularly the anti-work structure. Presidential nominee George McGovern also proposed a minimum income—in the form of a Universal Tax Credit. Ultimately, neither of these programs were implemented. Throughout the decade, many other experimental minimum income programs were carried out in cities throughout the country, such as the Seattle-Denver Income Maintenance Experiments. In 1996, under President Bill Clinton, the AFDC was replaced with the Temporary Assistance for Needy Families program. This would block grant funds to the states to allow them to decide how aid would be distributed.
