When I was in school, about 60 years ago, we saw 16MM film explaining how 'progress' was going to automate many things, giving us a 30 hr. workweek and lots of vacation time. Many scenes of happy families playing and going to visit grandma in flying cars while the house was vacuumed by robots...(presumably made in factories where daddy only worked 30 hours).

At that time, Japan was barely out of war reconstruction and just showing an interest in portable radios... and China was 75% still in the dark ages.

Even in the 1950s, I didn't see how it would work... "But, teacher.... if they can make robots do the work, how many men will they NEED..even at 30 hrs. a week?"
