funny thing is... there have already been basic income experiments in north america in the 70s [1]. As far as I know all experiments so far have never shown any substantial negative side effects and tended to show positive effects on work morale, etc. There has just not been the political will to try it on a large scale, yet. Might have to do with the fact that UBI will have a huge impact on the state and its duties. It takes courage for an organization to basically remove what has become a large part of its raison d‘etre.
