Yet our standard of living increased exponentially in that same time span
If you consider working longer hours for lesser compensation in real terms an exponential increase in the standard of living we may have to agree to disagree on this subject.
Furthermore, people are paying cash for all of these wonderful life fulfilling luxury items, right? How much did household debt increase during this period? For some, having the latest 60" HD television may be a pleasant diversion from the fact they are hopelessly in debt, and may never be able to retire, but again, I really wouldn't consider this an increase in the overall quality of life.
