Donella H. Meadows in Thinking in Systems:
Hunger, poverty, environmental degradation, economic instability, unemployment, chronic disease, drug addiction, and war, for example, persist in spite of the analytical ability and technical brilliance that have been directed toward eradicating them. No one deliberately creates those problems, no one wants them to persist, but they persist nonetheless. That is because they are intrinsically systems problems-undesirable behaviors characteristic of the system structures that produce them.
Very interesting book and a reminder to think outside the box of simplicity.
