Earlier quoted context omitted.
Welp, guess I was wrong.
Assuming you're referring to the discussion that followed your vouch, I know people who talk like that comment in person, and their tone of voice and body language makes it clear that they're reasonable and genuine people just with a different vocabulary. But it's impossible to tell online, with only text.
We are talking about something that is nonsense.
What are we talking about?
People ought to be able to work no more than six hours a day.
Really?
Why does anyone work eight? Or ten? Or twelve?
Did this 8 to 10 hour per day thing get sprung on people and forced upon them from nowhere?
No. Of course not. It's something that achieved a "natural" balance over decades (centuries?). And the balance has hundreds of variables driving it. From personal happiness to international competitiveness and productivity with even more variables across varied industries and cultures.
Nonsense is picking a number out of thin air, be it six or four hours and proclaiming that, not only will this work but it will result in happiness and a real improvement in employment figures.
It's like going into an ecosystem with some balance and killing off all the rats. There will be consequences. And they will likely not be positive.
You can't force a nation into a six hour work day without leaving behind measurable destruction. And this destruction would range from the personal (individual, family, kids, social groups) to corporate and national. You just can't do that and expect positive results.
This isn't about not liking the idea of working less and devoting more time to "living life". No, this has nothing to do with that. It has to do with the reality that these decisions exist in the reality of a very complex local, regional, national and international competitive marketplace.
A change of the sort being discussed would forcefully move away from a balanced position that allows everyone to earn a reasonable living, companies to remain viable while facing a myriad of competitors operating under different rules and society to function.
And so, proposing that people would be happy while facing a massive change in their standard of living, their ability to save for their future, feed their kids, take trips, have free time (because they will need two jobs), etc. simply isn't in alignment with reality.
To further propose that this would also improve employment is equally misplaced because this metric --the number of people being employed-- isn't a measure of anything other than a head count. A more useful measurement would combine head count with standard of living, savings rate, leisure time, quality of child care, etc.
These conclusions are faulty to such an extent that suggesting this approach would work could only be done from a less than lucid frame of mind.
In other words, it's nonsense and you'd have to be on dope to believe it would actually make society better.
Could we make such a thing work?
Yes, we could.
How?
Through massive global changes that are likely to require centuries to achieve. In other words, Star Trek territory. Not impossible, but, today, highly improbable because it would require dozens of nations to agree on terms and coordinate such changes over extended periods of time while making significant concessions.
