It only makes us poorer if the 13% work hour reduction is going to something less efficient than work, with regard to overall economic effectiveness.
With mincome didn't they determine that the work hours decreased was dominated by 1) young males entering the work force later due to increased high school completion rate and 2) females talking longer maternity leave?
If thats the case, then its possible that it made everyone richer if over the lifetime more educated workers and more cared for infants are more efficient.
*Note: I actually am a huge skeptic of basic income schemes as the math seems dramatic, but I think a simple "people work less hours" counterargument is overly simplistic.
