Published in the 1840's, it comprehensively compares national systems which promote industrial and agricultural development through tariffs and government support, notably the German and American systems, with the British colonial system of unrestricted Free Trade. It is a powerful indictment of the underlying motives and effects of the colonial system. The book has gone into extreme disfavour and total exclusion from college curriculums as these have gravitated to roles of corporate apologists or to reactions of Marxist and post structural ideology. It cogently presents, however, the argument against the world wide movement to limit economic sovereignty of nation states, and paints a grim picture of the inevitable result of unrestrained Free Markets, notably in the experience of British workers during the Industrial Revolution. The experience of the early to mid 19th Century, where these competing systems could be seen in very pure form by comparing the American and the British models, presents a compelling case for the National System List describes. Our current economic leaders do not want you to read this book, even as the leaks in Globalism start to bust down its dikes and even with a growing body of contrary modern opinion as to the benefit of Free Markets.
