Most people are using that extra productivity to have more toys. Houses are much larger than 70 years ago. People now commonly have AC in the house. Most people have a phone/computer in their pocket (the video phone of 1950s science fiction not only exists, and it isn't a room sized machine but something even kids have in their pocket). You don't have to - get rid of the phone and you save a lot of money per month - but most people have chosen not to. Maybe they just feel forced to, but it is still a choice and there are a few people who by not having them prove it isn't forced.
