Are you considering “having cheaper stuff” actually progress in terms of humanity ?

Ultimately price is just a measurement of how many resources it takes to make something, with the currency added in as the medium of exchange. A product being cheap means it is now easy for us to make; the previous price of the now-cheap product will be taken up by a better product.
But it would definitely be nice for businesses in general and employment law to stop being obsessed with 40 hours as a magical number. Working 4 8-hour days, or 5 6-hour days, or 4 6-hour days should be just be an option by default.
(And wages have to stop stagnating relative to prices so that the premise of "cheaper stuff" actually happens in the first place.)
