Everything in the study makes perfect sense. However one thing that's not discussed is change in culture and expectations. For example the United States is probably the only country where there's a general expectation that grandparents parents and adult children all live in separate homes... and most other countries multi-generation living is the norm. And perhaps some of those norms are starting to float into the United states. On the other hand no doubt the fact that people are not able to live to the traditional American norm is contributing to malaise. Still it feels a little simplistic to characterize everyone's goal is having their own home.

Maybe a way to handle this better would be to look at the size of the home because if a home can easily fit multiple generations it feels like a very different situation. Also it's somewhat arbitrary who happens to be the owner on the deed not to mention key questions like whether or not the home is truly owned outright versus largely in debt to a mortgage
