In my personal life and professional career I've come to look at the dynamics of "home ownership" and "suburbia" very differently than they are portrayed in articles like this. Two general points that guide me on this:
1. If you live in a suburban area and work in a nearby city, don't consider yourself a "suburbanite." You are an urban resident in almost every respect, and your socioeconomic indicators cannot be detached from your ties to the city.
2. Related to the previous point ... If you don't live and work in the same municipal or county jurisdiction, I'd say a lot of the characteristics of "home ownership" go right out the window. In fact, I'd suggest that the separation of home and work locations has been one of the most destructive features of suburbanization in the post-WW2 era.
Your argument fails because you don't consider the various levels of urbanization, e.g., village, town, city, Metropolis, Megalopolis. Also, socioeconomic indicators aren't necessarily bound by where you live. Ever hear of remote working?
For the last three years I’ve been working from home, as have many others.
Even before that, the places I’ve worked at were mostly in suburban office parks. Businesses realized decades ago that they could save a lot of money by setting up in the suburbs, where most of their workers lived anyway.
The trend started with the creation of the interstate highway system back in the 1950s. Cities were doomed at that point.
