Isn't the concept of a weekend at least as old as Sabbath, ie thousands of years?

Yes, but it was only recently “won”: that is, most of western society has had two days off per week (to varying degrees) for just over 100 years if my recollection is right.

And we will probably never get to three days off (for the majority of population) despite all the productivity growth etc.
