What happens when automation displaces a sufficient portion of the unskilled workforce that their value is less than 'minimum wage'? In an increasingly technical and automated society, what do we do about those who cannot adapt or become skilled enough to work in the increasingly technical workspace? We can either manufacture menial, useless jobs or admit to ourselves that HAVING to work is not necessary. We NEED to begin exploring Universal Basic Income to learn how to accommodate this in the future. It's either that or we let those who can't join the workforce suffer. I don't know that we're there yet, but we will someday. Sooner than we think.
