Just as Mother Courage looks to the Thirty Years’ War as a business arena, so too was World War II a commercial enterprise. The United States, as well as Germany and other European countries, converted almost all their national infrastructure to service the war; industry became focused on turning out war goods at ever-increasing rates. In the United States, the federal government spent $370 billion on World War II. Even before the U.S. entered the war, however, the American economy geared up to produce goods for war-torn Europe. This boom in production fostered a new age of industrial technology in the U.S. and would pave the way for the prosperity of the postwar years. Despite the frenzied production, which in the United States meant around the clock shifts in factories, there were shortages of consumer items all around the world. This was partially due to the scarcity of some raw materials, again because of the war. In occupied countries, shortages were the most acute. Small-time entrepreneurs such as Mother Courage were able to supply in-demand items and carve a profitable niche for themselves.
