Universal Basic Income (UBI) has been advocated in various forms by Thomas Paine, Andrew Yang, Milton Friedman, and Richard Nixon: a minimum income floor available to all Americans.

Scott Santens is a UBI proponent who has advised Andrew Yang on UBI, and is now senior policy advisor to Mike Broihier. He sits on the Board of Directors for the Gerald Huff Fund For Humanity.
