Note 600 — Chapter IV · : FRIEDRICH LIST AND THE NATIONAL SYSTEM OF POLITICAL ECONOMY

“Neither is it at all necessary that all branches of industry should be protected in the same degree. Only the most important branches require special protection, for the working of which much outlay of capital in building and management, much machinery and therefore much technical knowledge, skill, and experience, and many workmen are required, and whose products belong to the category of the first necessaries of life and consequently are of the greatest importance as regards their total value as well as regards national independence (as, for example, cotton, woollen, and linen manufactures, etc.). If these main branches are suitably protected and developed, all other less important branches of manufacture will rise up around them under a less degree of protection.” (National System, p. 145.)
