The first of last January, there was, in Mexico, an American army of 23,695 regular soldiers, and a little more than 50,000 volunteers, the number cannot now be exactly determined, making an army of invasion of about 75,000 men. The naval forces, also, had been increased to 10,000. Estimating all the men engaged in the service of the army and navy; in making weapons of war and ammunition; in preparing food and clothing; in transporting those things and the soldiers from place to place, by land or sea, and in performing the various other works incident to military operations, it is within bounds to say that there were 80,000 or 90,000 men engaged indirectly in the works of war. But not to exaggerate, it is safe to say that 150,000 men were directly or indirectly engaged in the Mexican war. This estimate will seem moderate, when you remember that there were about 5,000 teamsters connected with the army in Mexico. Here, then, were 150,000 men whose attention and toil were diverted from the great business of productive industry to merely military operations, or preparations for them. Of course, all the labor of these men was of no direct value to the human race. The food and clothing and labor of a man who earns nothing by productive work of hand or head, is food, clothing, and labor thrown away; labor in vain. There is nothing to show for the things he has consumed. So all the work spent in preparing ammunition and weapons of war is labor thrown away, an absolute loss, as much as if it had been spent in making earthen pitchers and then in dashing them to pieces. A country is the richer for every serviceable plough and spade made in it, and the world the richer; they are to be used in productive work, and when worn out, there is the improved soil and the crops that have been gathered, to show for the wear and tear of the tools. So a country is the richer for every industrious shoemaker and blacksmith it contains; for his time and toil go to increase the sum of human comfort, creating actual wealth. The world also is better off, and becomes better through their influence. But a country is the poorer for every soldier it maintains, and the world poorer, as he adds nothing to the actual wealth of mankind; so is it the poorer for each sword and cannon made within its borders, and the world poorer, for these instruments cannot be used in any productive work, only for works of destruction.
