So, I was having a friendly debate with someone about our foreign policy. One of my favorite ways to debate socialists is using the broken window fallacy. it just makes so much sense and can show why certain things like war, welfare, and taxes are inherently wrong and they decrease an economy's net wealth.
However, without debating the morals of going to war with other nations, and simply focusing on the economic aspect of it, my friend had a question for me that I honestly could not, and still cannot, answer:
What do you make of conquests in which you acquire territories and/or have other nations pay reparations? Would it then not be a net increase?
I do not see the difficulty, unless I am misapprehending the gist of the question. Most of the time destruction results in a net loss of value. Economies "grow" when value is added. I go to the sand pit, load my cart with sand, take it back to my studio, put the sand in the kiln and after it melts I start making glass objects. I have taken a raw material generally viewed as being of some net value, say X, and transform it into something of a new value, X'. So long as X' > X the net worth of the world has been augmented, all else equal. This is what we call "
added value".
Warfare rarely, if ever, results in
material added value. This is especially true with modern, mechanized, engineered warfare due to the extensive destruction that results at the press of a button. In the long aftermath of war there may again be added value conditions prevalent in a give place, but before that can happen, the negative ledger entries of the destruction must be balanced with reparative activities. All those activities add zero value to the books, save to reinstate some former level of net worth. A good example is the Word Trade Center site. The rebuilding has not augmented the overall value of, say, Manhattan real estate (just to focus on a single result of the activity) until what has been built precisely matches (by some standard of measure) that which was lost. At that point you are back to relative zero-sum. Anything you add thereafter may be considered as added-value.
Does this make sense?
Therefore, while one party may benefit from "war reparations", they may still be devoid of added value because what was expended (war costs) went into nothing materially positive. It was devoted to killing and wreckage of that which presumably had value prior to hostilities and the destruction of which attenuated the ledger balance. So then, for example, Germany's reparations to the UK probably added little, if any, because that money would have presumably been spent on rebuilding all that Germany destroyed during hostilities. Germany, of course, loses out completely because those monies were unable to be applied to the repair of their own devastated cities and industry.
Much as the destruction of net worth by the little bastard hired by the local glazier to break shop windows so he will benefit from the destruction, the same may be said of nations engaging in warfare. The notion that was put forward that the war in Eye-Rack was a GOOD thing for the world economy because Haliburton was awarded billions in heavy construction contracts flies in the face of anything remotely related to truth an intuitive good sense to honest men whose intellectual faculties are nominally intact. The example of warfare does indeed track very closely with that of the broken window fallacy. There is NOTHING good about war. It is ALWAYS a net loss even when justified. Destruction of value is costly and it almost never makes things better. There used to be a gorgeous brownstone (Lutheran? Methodist?) church on 63rd st. in Philly. I used to drive past it often and would marvel at its lovely architecture and construction. One day as I drove past I was utterly horrified, and I mean that literally, to see an excavator demolishing this profoundly beautiful structure. Its replacement? Just what the world needed - another strip mall. There's the Broken Window Fallacy at work, IMO.
Being the open-minded person I am, I conceded that I believed he was right. Again, without taking into consideration morals, is there any flaw in his logic? Would the spoils of war afterwards not make up for the net loss during the war and more?
Please help me understand.
Certainly not because the game becomes ZERO-SUM at best, and is often negative sum for the reasons cited above. As I write before - destruction costs in innummerable ways, the most obvious form being in gross material terms. So no, your opponent was not only incorrect, he was grotesquely so. It takes a special brand of blind to see it the way he does and sadly, far too many people are blind in this way.
