My biggest observation is the large scale social impact of people not needing to work. In the US many people got unemployment benefits and were unable to work.

My biggest observation is the large scale social impact of people not needing to work. In the US many people got unemployment benefits and were unable to work. We also had nationwide protests by both liberals and conservatives for various causes. Some looting in there, aggressive police response and crazy people waving guns. It seems to me that given UBI people will spend their time championing their causes at the expense of those who are working (blocking areas with protests is just that). Seems a very unstable dynamic as I'd imagine both conservatives and liberals would escalate until mass violence breaks out.
