Considering how some intelligent individuals have predicted that the technological singularity (the AI that can self-improve, thus being superior to man in every way -very- fast) will come to be within this century, it stands to reason that the automation and AI that precedes that will essentially wipe out the low income menial labour roles that the beneficiaries of the 'basic income' currently occupy.
That is a lot of people that the economy wants to be able to spend money in order to keep it going, and taxes flowing.. there's little opportunity for the vastest majority of those workers to suddenly turn to work within higher education without some gov assistance.
Who knows how many higher educated roles that there will actually be a need to fill for that matter? A human workforce could eventually be rendered ENTIRELY pointless in developed economies, and then what do we do with the old adage 'Get a job'?
