I tend to agree (mostly) with him. I think demographic trends favor the urban areas o=ver suburban. But I wouldn’t say the suburbs are NEVER coming back. For two reasons:
1. There might be economic factors that make living in the suburbs opr exurbs more favorable in the future (e.g. high prices in the urban core. We saw this with many people moving to Riverside County in the early 2000’s. Technologies such as efficient vehicles or acceptance of virtual workplaces could also impact costs to live away from urban centers.
2. Generational tastes change – Each generation tends to buck things that the previous generation favors. Right now it is desirable to live in urban areas. In 20 years, kids that grew up in densely populated areas might want to spread out more and live differently than they grew up. Tastes and trends can change a lot over 20 years.
