The McMansion sprawling hell suburbs we have are just ugly and awful, and incredibly boring. To provide people a place to live outside the city is stupid, the city is where everything interesting is, why go there just to work?
It is stupid, and not just in the subjective sense - after all just because intelligent people prefer stimulating urban environments doesn't mean dullards should to - but more importantly in the practical sense.
It is simply enormously costly to house people in suburbs and force them all to own cars and commute. Not only are cars ridiculously expensive, and wasteful ways to move people, the act of driving is a tension causing bore. To live in a place where you do not have to have to horrible burden of car ownership is such a feeling of freedom.
