Primary income-support welfare programs that could be consolidated into a single basic income include: earned income tax credit (EITC), Supplemental Nutrition Assistance Program (SNAP, formerly known as food stamps), temporary assistance for needy families (TANF), and supplemental security income (SSI).
In 2019, the US spent $70 billion on the EITC, $60 billion on SNAP, $31 billion on TANF, and $56 billion on SSI. In total, over $217 billion was spent on these programs alone.
