You could not have evolved a complex system like a city or an organism - with an enormous number of components - without the emergence of laws that constrain their behavior in order for them to be resilient.

Slums could be thought of as the development of a special organ, or they could be thought of as a tumor that's grown, and in some ways is unhealthy and could ultimately lead to the city's destruction. My own feeling is that slums are probably a bit of both.

Life is extraordinarily resilient. It's been around for over a billion years.
