Myths of rich and poor

"As of 1970, for example, only about a third of American homes had both central heating and air conditioning, while more than four-fifths had both in the 1990s. Moreover, the homes themselves were more than one-third larger. "

That's kind of funny in a way. That's like how people in the 1990's were less likely to have a cd burner than now, or dvd burners. Or how about cell phones? Not everybody had one back then. Or even telephones. Or anything else that started out as a base, unrelaible, expensive and slow service and through the wonder of technology developed into something better and cheaper to maintain, thus lowering cost.

I wonder how many people had electricity when it first "Came out" versus now. Or how many people in the 1970's were driving cars versus in the early 1900's. Was the entire point of that article to point out that civilization has developed through technology? Thanks, I needed to know that I wasn't living in a cave somewhere in Pakistan the size of my bedroom. I couldn't see that for myself.
