Actually, American suburbia is responsible for the widest diffusion of land ownership in history (even if it is only a 1/4 acre or so). So it has got that going for it.
I can see this. It tends to be the "safe" middle group between urban and rural while having none of the benefits of either.
I guess it all depends on what you want. From my perspective suburbia has all the advantages of both without the disadvantages.
