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 propose? Other options used in the past were typically state provided bread and circuses and/or waging war.
How soon is "soon"? I don't know about Ireland but the US unemployment rate remains near record lows. We still don't have robots that can snake out a plugged toilet.
Your entire idea of economics is backwards.
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.
