Excellent article. Thank you for posting.
I guess the question is, what’s next? some factors to consider. Birth rates are plummeting (Cost of raising children and couples marrying later), Healthcare costs continue to rise, and we are going to be left with a large inventory of three and four bedroom homes that are not going to be a fit for smaller nuclear families. I also saw some stats that job relocation is also down substantially. People are valuing staying in an area, benefiting from family, etc. and technology is enabling that.
Hard to predict, but will we be a society that reverts to more extended family structure in a geography? Parents moving in with children to defray costs.
