It's called productivity driven deflation. A high income is determined not by number of commas in the income, but by how much you can buy with a given amount of money. $6,000 used to be a high income. That is no longer true, because money printing outpaced the productivity gains.P.H. Dexippus said:
Universal High Income is the dumbest idea ever. Why not just have the government declare that $1 dollar bills are worth $1MM dollars? See, poverty solved.
What happens when productivity gains outpace money printing? Prices fall. What do politicians get to do when prices fall? Increase the rate of money printing. UBI happens and you never saw it coming and it didn't create the inflation you expected, because the entire economy got automated.
The restrictor on productivity is going to shift from being a human labor + energy problem to a purely energy problem and without the restriction on human labor energy becomes abundant.
