I&#x27;m not aware of any empirical or historical justification for the range 28-56. People are indeed seldom happy unemployed, but I haven&#x27;t seen any evidence that people would be unhappy on e.g. 14 hours&#x2F;week (of course it&#x27;s very hard to control for status aspects).<p>The kind of person who can cash in for millions is an outlier in many ways - the working habits of such people say very little about those of the general population.
