From Chapter 17:
In addition to the unimaginable loss of life, there were billions of man hours of human effort invested in the construction of roads and bridges and railways and skyscrapers and canals and factories and homes that were simply obliterated when they were turned to rubble by smart bombs or turned to glass by nuclear chain reactions. There are some learned people who have suggested, quite adamantly, that war is good for the economy, that war creates employment and demand and that demand foments economic growth. Perhaps they had a point! For those who had survived the bombs and then the subsequent disease, and then the hopelessness and despair, there were quite a few well paying jobs to be had because there were many, many jobs to be done and vast, vast numbers of laborers had been removed from the available workforce.
Of course, the exorbitant wages paid to these remaining workers didn’t really buy anything because there was nothing worth buying that was being made, few roads or trucks left to deliver any of it, and few storefronts left standing from which to merchandise it. The things that were still being made were mostly just more bombs, gunships, bullets, tanks, planes, missiles, helmets, and body bags. No civilians really wanted to spend their hard earned wages on that kind of stuff, so the gainfully employed survivors deposited their exorbitant checks and went home to their three standing walls and partially roofed, bombed out houses, ate their rutabaga pies, stared at test patterns on their 225 inch, high definition televisions, and talked about how good the war had been for the economy.
With nothing to buy and their money stashed in their bank accounts, the bankers turned around and lent that money back to the governments to build even more bombs, gunships, bullets, tanks, planes, missiles, helmets, and body bags. So in a sense, everyone ended up buying war materiel whether they wanted to or not. It should not go without mention that the very people who suggested that “war was good for the economy” were, with few exceptions, also employed by the very same people who declared the wars in the first place.
