What would “basic income” look like?

The usual "welfare" consists of 6 or 7 programs, although there are actually about 120 transfer programs--TANF, Medicaid, SNAP, WIC, housing, Utilities, CSFP (packaged commodities for low income), School breakfast, lunch and snacks. That doesn't count all the non-profits and church programs. There are 8 states where this amounts to earning more than $25/hour, and no taxes. In most states it's worth more than a $15 minimum wage since it's tax free. It's a high of about $49,000 in Hawaii and low of $17,000 in Mississippi. Poor people aren't dumb--they'll probably object to their Democratic congressman if he tries to fool them with that.

TANF provides financial assistance to help pay for food, shelter, utilities, and expenses other than medical.

Medicaid coverage provides all-inclusive care for eligible children younger than the age of 19, with particular emphasis on primary and preventive care in keeping with its Early and Periodic Screening, Diagnostic, and Treatment (EPSDT) methodology.

Other types of Medicaid insurance, such as the Healthy Start/Children’s Health Insurance Program (CHIP) provide enrollees access to equivalent Medicaid coverage. CHIP is a bridge program that extends Medicaid enrollment to low-income or at-risk children and pregnant women who would not otherwise meet the eligibility requirements. CHIP covers nearly all costs associated with pregnancy, prenatal care and birth for income-qualified pregnant women of any age.

SNAP means supplemental nutrition, but you can eat quite well with it. You’d need a PhD in government speak to figure out the rules. https://www.fns.usda.gov/snap/eligibility#What are the SNAP income limits?

WIC is Women Infants and Children as supplement for mothers with young children.

There are numerous housing programs.

Utilities is to help with costs of heating.

The National School Lunch Program is a federally assisted meal program operating in public and nonprofit private schools and residential child care institutions. It provides nutritionally balanced, low-cost or  free lunches to children each school day. The program was established under the National School Lunch Act, signed by President Harry Truman in 1946.
