CHAPTER III THE COURSE AND CHANGING NATURE OF UNITED STATES PRODUCTION AFTER 1860--AN OVERVIEW It is difficult to grasp completely the amount of economic change that has occurred within the United States in the past hundred years or the speed at which it has taken place. Only two adult lifetimes, put end to end, have passed since 1860, while two thousand years separates today's man from the birth of Christ and the power of Rome, four thousand from the strength of the Egyptian empire, and ten or twelve thousand from the time when men first became husbandsmen and herdsmen. Yet, in some respects, the lives men lived in 1860, the sorts of things they produced, and the methods by which they produced them were as similar to ancient modes as to those of present day. The economic progress of the United States since 1860 involved radically new products, machines, and production methods as well as the production of greater amounts of goods and services. Advances in quality, in product types, and in production techniques complemented increased production levels that put more of the staples of life as well as luxuries into the hands of common people. 29 -
