Law of Diminishing Productivity

In his excellent book The Breakdown of Nations the maverick economist Leopold Kohr makes several stunning yet, upon reflection, commonsense observations. He points out that small states have tended to be far more culturally productive than large states, that all states go to war but that big states have disproportionately bigger wars that kill many times more people, and that by far the most stable and advantageous form of political organization is a loose confederation of states, each so small that none can dominate the rest. Kohr arrives at his conclusions by a process of reasoning by homology (viz. analogy) by analyzing many of the problems of modernity as different manifestations of the same underlying problem: the problem of excessive scale.
