3. _For a high efficiency of production, as a whole, conditions must favor the best organization and direction of industry._ Industry is dependent primarily upon natural resources. Climate, rainfall, iron deposits, fuel, supply of wood or coal, predetermine in large measure the limits within, and the direction in which, the industry of any community can move. The progress of production depends also on an increasing efficiency of labor as embodied in individual men, and upon social and political conditions making possible an increase of capital. But--a condition as important as any of these--production is dependent also on a wise combination of the factors. Social, political, and economic conditions must be such as to call forth the factor of direction and control of industry, to make possible industrial progress. This is one of the greatest sources of America's superiority to-day. It has been strikingly said that it is now no longer "young America and old Europe," but "old America and young Europe." America is older in industrial experience; Europe, with undeveloped resources, awaits the touch of American methods and machinery. There are dynamic forces in American society not present in equal degree in any other. It is therefore not alone the great resources of coal and iron,--equal resources may be found in unexplored parts of the world,--it is the dynamic social forces, invention, enterprise, and organization, which have brought America to the forefront in industry. Her natural resources have thus yielded an incentive and a premium to enterprise as a sort of by-product. Absence of caste, political liberty, the democracy following the spread of the frontier, have not made it possible for every one to succeed, but they have made it possible, as nowhere else in the world, for real ability to scale the barriers of birth, poverty, and hardship. A conservative population never can equal a progressive population in industrial efficiency. It has been remarked that America has little to fear from Oriental competition so long as the avenues of education and enterprise are open to her young men, insuring her the highest capacity in the organization and direction of industry.
