> No, people work more than they currently need to because they are exercising prudence, common sense, and planning for the future. Which every adult human being is supposed to take responsibility for doing for themselves, and not expect a "trust fund" to magically take care of for them.
It may not be materially possible for everyone to actually do this within our current economic organization in light of automation. People that benefit from UBI may very well be responsible and organized.
We can twist this a little and say that the responsible and organized thing is to plan for automation, to develop skills that make sure you aren't put out of work, etc. Personally I find that position logically valid, but I ideally would push for UBI while also making sure I have a good chance for not needing it.
A cynical take is that UBI is just enough to ensure the masses of unemployed would be complacent enough to not riot.
