Earlier quoted context omitted.
The trouble is that paying a few people to not work is very very different from paying everyone to not work. We need people to work to produce the things they need to live. As long as this remains true, UBI can never happen. This fantasy of being able to live without working is out of touch with the cold hard reality.
The problem is soon (and to some extent currently) there won't be enough work for everyone, and there definitely won't be enough to support them at a historical lifestyle level. I guess those people continuing to live (or live semi-well) would be fantasy to you. I'm not sure where society will go at that point. The western world has sold a 'we are improving your life' story to get buy in from the masses. What do you…
There is more than enough work for everyone right now, and (outside of recessions) we will not run out: https://en.wikipedia.org/wiki/Lump_of_labour_fallacy
As more and more work is automated, the lifestyle level increases rather than decreases. Automation lets you produce more with the same amount of labor, increasing productivity and raising the standard of living. This is the sole reason we're not subsistence farmers right now.
War does not help the masses; it is purely destructive and one of the worst things you can do for the economy in the long run.
