Tribalism is Inefficient
Bloodless civil wars are being waged across the world. The tribal warfare within most nation-states prohibits productive government and leads to vast inefficiencies. The greater the political conflict, the more inefficient an administrative body becomes.
The bottom left corner represented here as the Ideal Range is what civilization should strive for. In the Ideal Range, political opposition leads to constructive challenge of policy and government spending packages, which ultimately improves the result. Adequate challenge improves outcomes, but there is a point in which challenge becomes an impediment; this is when the line crosses into tribal conflict.
The top right of the graph represents a total civil war, where both sides are solely focused on destroying one another. Total civil war is generally an extremely inefficient use of time, as progress in most other areas of civilization cease to exist. It should be noted that certain total civil wars can have a justified rationale, if there are ethical, moral, or social humanitarian betterment principles at stake. Most nation-states fall somewhere in the middle of the range, where tribal conflict leads to government inefficiencies.
