In manufacturing, where mechanization and the use of chemical processes are much easier, it is easier to raise productivity than in services. In contrast, by their very nature, many service activities are inherently impervious to productivity increase without diluting the quality of the product.

It takes time and experience to absorb new technologies, so technologically backward producers need a period of protection from international competition during this period of learning. Such protection is costly, because the country is giving up the chance to import better and cheaper products. However, it is a price that has to be paid if it wants to develop advanced industries.

Manufacturing is the most important...route to prosperity.

Self-interest, to be sure, is one of the most important, but we have many other motives - honesty, self-respect, altruism, love, sympathy, faith, sense of duty, solidarity, loyalty, public-spiritedness, patriotism, and so on - that are sometimes even more important than self-seeking as the driver of our behaviors.
