https://en.wikipedia.org/wiki/Welfare_queen
Since then, the phrase "welfare queen" has remained a stigmatizing label and is sometimes directed toward black, single mothers. Although women in the U.S. could no longer stay on welfare indefinitely after the federal government launched the Temporary Assistance for Needy Families (TANF) program in 1996,[1] the term remains a trope in the American dialogue on poverty and negatively shapes welfare policies and outcomes for these families.[2][3][4][5]
