But that's not what they said, they said they want to work less. As the GP post said, they'd still be working a full week.

I do think this is an interesting point. The trend for most of history seems to have been vastly increasing consumption/luxury while work hours somewhat decrease. But have we reached the point where that's not what people want? I'd wager most people in rich developed countries don't particularly want more clothes, gadgets, cars, or fast food. If they can get the current typical middle class share of those things (which to be fair is a big share, and not environmentally sustainable), along with a modest place to live, they (we) mainly want to work less.
