Nothing is of greater importance to national defense than the morale of those who do the actual work, the men who pump the petroleum, roll the steel, build the ships and planes. An ounce more of spirit along the assembly line is worth more than a correspondingly higher percentage of armaments in a clash of troops. This is because modern wars are won by industrial strength, a fact that we are almost tired of hearing repeated, but the truth of which we are observing with every passing month of the present war.War industries require raw materials, trained leadership, and sufficient funds to support the costly effort. A nation needs all of these. But all depend for their success upon the efficiency and ardor of designers, foundrymen, and machinists. Do they put their minds and backs and hearts into their work? Or do they merely go through the motions?Organized labor may be fitted into a war economy in one of several ways. The workers can be virtually enslaved, as in Poland, and forced to labor with armed sentries standing over them. This method has never proved very efficient. Another way, which Hitler and Mussolini are using, is to appeal to the emotions of patriotism, to work men into a frenzy which must then be sustained.
Mankind is sectional in outlook, carving the world into little compartments with mile upon mile of boundary lines. Technology, on the other hand, is inherently universal in outlook; nature's laws operate as infallibly in Spain as in China, in Russia as in Australia. The substances which it uses are scattered widely over the earth without respect for human conventions. In the collection of raw products and the transportation of finished goods, its purposes are economic, not political. The engineer, then, in applying his rational skill to the world's haphazard system of political areas must necessarily cut across artificial regions with a variety of works. The railway needs no introduction as a map-slashing agency. It has pierced the Alps, connecting Switzerland and Italy by way of the famous Simplon tunnel; it has crossed the towering Andes, linking Argentina with Chile; it has stretched out through Siberia, tying China and the Pacific with the countries of western Europe; and it speeds the traveller through a veritable maze of Balkan nations. Electrical designers, creating superpower nets of transmission lines, run wires with utter abandon across national and local frontiers, joining Switzerland and France over the Alps in one net, and North Carolina, South Carolina, Georgia, Alabama, and Tennessee in another. The production manager, turning out automobiles, airplanes, watches, and a flood of other commodities, seeks to distribute his products in every clime and under every flag. The engineer, in short, is a universalist, however intense his patriotism, and cannot function efficiently without traversing human boundary lines.
