In our ordinary thinking we seldom go beyond the notion of individual capital - that is, capital possessed and directed by individuals. Society, also, has considerable capital which is of no small amount and importance. Factories and department stores install automatic sprinklers, which we agree at once is capital. Sprinklers lessen the fire hazard. So does the city fire department with its heavy investment in buildings, trucks, ladders, and other equipment. Both serve the same purpose; both represent capital investment, one by individuals, the other by society. In extending this notion we find, for example, that government buildings with their furnishings and equipment parallel individual capital investments designed to furnish the same or similar services, and as such they are capital.
