If you can so much as imagine a society organized around some other source of happiness, there’s your evidence by counterexample.
Working is objectively good for your health. Stopping work is associated with an extremely large increase in mortality risk, for both healthy and unhealthy people.
Any alternatives must weigh the resulting death it will cause.
If I had a study that showed increased mortality in people who had owned a parrot for 50 years in the year after that parrot died, you wouldn't cite it as evidence of the basic human need for a parrot.
"they still do" is just begging the question. Plenty of people live without working. We're ruled by people who don't work.
I think imagining a world where people are universally able to find purpose outside their employment counts as "changing the definition of people". Perhaps less difficult of a change than making us not dependent on oxygen, but still a big enough change not to clear the bar.
> Plenty of people live without working.
A minority of people live without working. And many people who do not work are profoundly unhappy with that state of affairs.
> We're ruled by people who don't work.
That's a cute thing to say, but isn't a serious rebuttal of anything.
If you tested the claim it wouldn’t tell you about human nature, because it’s possible (and I think likely) that most people are simply conditioned to believe they need purposeful work to be fulfilled, so you could just as well argue that if society were to be radically re-engineered, it would be worthwhile to re-engineer it at the psychological level (such that no one felt the need to work), rather than the economic level (such that work was made available to everyone).
> We're ruled by people who don't work.
I don’t have any data to support this but I suspect the majority of those people that we would characterize as happy are still engaged in an occupation (not a “job” as such, but purposeful work that goes beyond mere leisure). I’ve seen dozens of well-to-do retired boomers who waste away on Twitter or YouTube and don’t seem to do much of anything anymore, which is what I’m guessing is the behavior you’re imagining when you talk about oligarchs not working, but I don’t see much evidence that the oligarchs are like that; most that I can think of have made no indication that they will ever retire. Now, granted, work looks a lot different if you’re Warren Buffett, but what we’re looking at is not the social benefit of work as such but the impact of structured, purposeful activity on an individual’s psychological sense of wellbeing. In that sense, I think it’s unlikely that these people would disprove the premise.
you can't claim an invention is invalid because there are no "studies" that show such an invention has already existed and succeeded, you'd by definition never invent anything!
I absolutely can imagine a society organized around some other source(s) of happiness, but the fact is we don't have that society, and humans are not acclimated to that society. Humans are acclimated to the society we have, and there's plenty of research out there showing that many, many humans derive a significant chunk of their self-worth and life's purpose from their jobs.
And when they lose their job and can't find satisfying work, their quality of life is meaningfully impacted, in ways that cannot be fully explained by the financial impact of losing a job.
Another fine example is retirement. Many older people end up finding work again in retirement, not because they need the money, but because it helps them find purpose. Others don't retire until the day they die because they can't imagine a life without work. Yes, some people love retirement and are happy and thrive, but there are also many who aren't and don't.
Men, or women?
Not trying to raise gender role controversies. It's just been my observation, throughout my life experience, that men, as the primary public-sphere producers and providers, are much more tethered to public-sphere occupational identity than women. This seems validated in the experience of the structurally unemployed, e.g. in the former industrial regions.
As women are 50% of the population, give or take, I expect the politics of this might flow differently for them than for men, as a bloc.
