While I wholeheartedly agree with you, I think we should be careful with this discourse.
Rather than increases in productivity, increases in production should be emphasized. And yes, you cannot increase labor production without an increase in productivity, everything else equal.
Iirc, increase in production is about 40%. So working Monday to Thursday, you produce the same as someone, working 5 days produces Monday to next week's Tuesday morning.

Research is not solid, but promising.
