I’ll have to read those studies more closely. And I hear you on the truck driver argument. That said, I’m sure less stressed/less tired truck drivers cause a lot fewer accidents. Which may have an impact on insurance premiums for companies that are in that business.
I guess my point is economic impact can be measured in various ways and it’s possible that everyone working less (and the 10% paying the other 90% of us a fair wage), will be a net benefit for society and the health of the individuals in society, and thus, a net benefit for the economy.
As a non-office worker (worked in food service my whole life), I’ve seen the direct effects on mental and physical health caused by being overworked and under paid. And those negative effects certainly spill over into the quality of service, as well as the potential for a accidents at work.
I know that’s anecdotal, but I think it also is a very reasonable observation that passes the common sense test anyway.
