To summarize:
You would think that with such amazing increases in productivity and technological growth that that would mean not as much work would be required to make the economy go. If it took 40 hrs/week to make the economy go in 1980, and we are 50% more productive now, then wouldn't it make intuitive sense that everyone would only have to work 20 hrs/week to maintain a similar standard of living (I'm just giving an example, I don't know how much more productive we are)?
I think everyone understands that technological growth has improved the standard of living. There are treatments for medical issues that were once incurable, etc. There aren't nearly as many jobs that rely on physical labor as there once were. Working hours are lower than they used to be (although the move from the 12 hour work day was largely the cause of a social change, that is, workers demanding shorter work days to have more of their life).
Thinking more recently though, like 1980s-1990s, has much really changed? Many of the quality of life improvements that I mentioned were around then.
Everyone in a modern industrial society pretty much needs the following:
- A car (or public transit, although it doesn't seem reliable enough for anywhere but big cities)
- Car insurance (this is mandatory in most US states)
- Health insurance (if you don't have it better hope you never get sick or you're bankrupt)
- Food
- Housing
- Heating/Cooling
- Education
The cost of health care in the United States has been increasing double the rate of inflation (I hear, not completely sure)
The cost of housing is more and more expensive, even if you get a moderate house. If you get a house too small then you risk not being able to sell it later because "most" people want a "nice" house.
The cost of an education has increased way faster than inflation. If you want to make enough money to live decently you had better get a four year degree (expensive, lots of work), start a successful business (not that easy to do) or get some very prestigious two year/technical degree (not a lot of these). II would say for most people that don't go to college though their fate is that of low paid work.
Right now it seems like we're worse off. Everyone works about the same amount, and has similar levels of stress, but we haven't gotten any significant improvements to the basics in a couple decades at least. Having the internet and all these technological advancements is nice, but if they aren't making the fundamentals cheaper then what is the point?
I'm sure there are some things related to quality of life that I've taken for granted, but I wouldn't consider there to be any meaningful economic progress until the "middle class" wage is high enough so that people could afford the basics with 30 hrs/week or less. I find it problematic for those that value their free time (and reduced stress levels) that there is no way to choose to live a little simpler but work a few hours less a week. You can work really hard and get minimum wage, or you can work really hard and get paid $100,000 a year. However, the end result is still the same: you are going to be working really hard for 40 hours a week. I can't tell you how much more enjoyable it would be to be able to work 30 hours a week in place of having a fancier car or a bigger house. Your bigger house or fancier car isn't going to make that extra 10-15 hours you spend at work any less frustrating, mind numbingly boring, and/or stressful.
Ultimately I feel like this problem isn't going to be solved by technological improvements, it is going to have to be fixed by reorganizing society in some way. The only reason we aren't still working 12 hour days is because workers protested and employers saw some medical research that said that in general, working that much actually made employees less productive in the long run.
