The following information was published in a national monthly financial magazine a few years ago. I don't have the sources for the specific data anymore, but you'll have to trust me when I say I did have the sources when
I wrote the article. 
And I realize that this info is now a few years old but I don't believe things have changed much since I published this:
The average home is twice as large as in 1950, but the average family is 13% smaller. Fewer people are demanding much more space.
Purchasing the average new car today requires fewer months' worth of family income than it did in 1950. The number of cars per adult is 50% higher than it was then. Years ago, it was not uncommon for a husband and wife to share one car. Today, both spouses likely have a car and often, licensed children do, too.
In 1960, Americans spent 15% of income on groceries vs. only 7% today. Our real downfall is eating out. In 1990, 42 cents of every food dollar was spent in restaurants, double the amount spent a generation ago.
Every year, more than 16 million Americans visit foreign countries. In 1950, the number was 680,000.
The average American consumes twice as many goods and services as he/she did in 1950 and ten times more than in 1929.
As a nation, our standard of living has continued to rise and that does bring with it added costs. But when we look at our parents' or grandparent's generation and what things cost then, we simply aren't comparing equal lifestyles. If you are willing to live in the manner in which your parents or grandparents lived 50 years ago, you could get by on far less money and direct a lot more of your income to savings.
