What's the stereotypical American Dream: a house, a yard, a family, and white picket fence. And while a stereotype, I think most Americans would prefer to have some sense of personally owned space in their domicile. A traditional city wouldn't be very good at providing this.

There's certainly a cost to be paid for this individual space, which the post did a pretty good job of pointing out. But to completely ignore the benefits of suburbs and why the culture created them in the first place is not a recipe for change.
