But iceboxes were certainly common, as were fans. I guess my point being: the people of the 1920s weren't savages, and while it's obvious that they didn't enjoy the same comforts we enjoy today there were still many conveniences that did exist.
The past is a strange place, with odd customs, but it's not totally alien or barbaric.
With an extra 3 days of leisure every week I'd think I could handle not driving 80 mph on the highway. There are pictures of these 20s and 30s cars at the top of dirt roads in the rocky mountains so what ever power they had still let them go places.
Do I really need all the car that the civic is?
And for an extra three days of leisure a week, you'd be giving up not just driving on the highway, but indeed a whole load of things.
Again - for most things, nobody is making you consume these additional goods and services above the 1930 average. But, as we can see, they're quite popular and people apparently prefer to work more and consume more rather than work less and consume less.
