I don't believe that is all down to the changing demographics of the labor force. Another aspect is the availability of land in desirable locales (i.e. close to metro areas). There are more than twice as many people in the U.S. now as there were "in the good old days" (by which I'm referring to the 50s and early 60s). And houses have gotten larger. And on top of that, people have been generally expressing a preference toward urbanization, with less than half as many people living in rural areas today compared to the 50s. All these factors have had a significant effect on housing prices, the dominant cost most American families pay.
