&gt; the first real question to be asked really is, why does everyone need to commute to the same place in the same time?<p>&gt; If people are really required at a place physically (i.e. cannot do their work remotely) urban cities should become decentralized with several business hubs closer to the suburbuan areas.<p>Yes, other business hubs are called &quot;other cities&quot; and &quot;towns&quot;.  There&#x27;s a reason people pay a premium to pile into the same city, and you can&#x27;t wish away the large benefits of density, both in terms of housing and in terms of businesses.
