Suburbs are unsustainable?

[Downtown diva]

Many times on this board, I have read about the bad side of living in the suburbs....

one person says that the majority of the suburbs are unsustainable
a couple people claim that the suburbs are a bunch of parking lots, malls, etc...
still other people claim that the burbs are "vanilla"

so here's my question...and I am not trying to be a smart ass....

explain to me, why a family of four, making over 100,000k per year would want ot move to the City of Detroit. Explain to me what schools their children would go to. Also explainwhy the city is a better choice than these suburbs.

I don't see it, but I am willing to listen to these benefits.
