US home ownership has gone up and down between 64% and 69% in the past 30 years, currently at the low end of that. But at the same time, the average new house went from 1,600 to 2,500 sqft.
Thirty years ago, how many people plopped down $5k for a TV? $700 for a phone? $150/month for telecom?
Life expediency has increased by 6 years from 1975 to 2010.
And to top it off, we're working less than we ever have. Average hours per year: 1,900 (1950), 1,800 (1970), 1,725 (1990), and 1,700 (2010).
Despite the "back in my day" doomsaying, on average, our quality of life has never been better.

My two cents why:
Cent 1: In a globally connected world, we are painfully obvious of the millions of people living more comfortably than us. When it was just Mr. Jones down the block, it didn't feel so bad.
Cent 2: Culture and priorities have changed. Rural population has been dropping for decades. People are more likely to rent a 500 sqft apartment in a large urban center than rent/buy a 900 sqft house in a town of 20k. Not a bad thing, just a different thing, and we have to take into account the whole picture.
