Jeremy Kauffman makes an interesting observation about the difference between Western and non-Western societies based on their prosocial behaviors, in this case traffic systems. It's a good example.

Being a polite driver is not self-interested behavior because one can often go faster by being antisocial. But in much of the world, traffic looks like the image on the right because most people won't sacrifice to maintain a prosocial system.

Western traffic systems, our parks and common areas, much of what is special about our societies reses on this type of prosocial altruism (non-kin fairness) and when a population falls too low on this attribute (or never had it in the first place) everything decent falls apart (or never gets built at all).
