Reconstruction is merely a special case of economic progress. If we are to understand its problems thoroughly, we must examine what is meant by economic progress and try to discover how it comes about... Economic progress is not altogether easy to define and is even more difficult to measure. Nevertheless, the phrase clearly corresponds to a meaningful idea. We have only to contrast a savage society with our own. In a savage society, the same customs, the same techniques, the same ways of doing everything, from ploughing to praying, are maintained generation after generation, son following exactly in the footsteps of his father and daughter in the footsteps of her mother, without deviating an inch from the well-trodden way. In modern civilized society, on the other hand, there is constant change and flux; we are constantly improving on the methods of our ancestors, and indeed one of the surest ways to discredit anything is to call it "old-fashioned!"
