IN this book I have endeavored to determine whether protection or free trade better accords with the interests of labor, and to bring to a common conclusion on this subject those who really desire to raise wages.I have not only gone over the ground generally traversed, and examined the arguments commonly used, but, carrying the inquiry further than the controversialists on either side have yet ventured to go, I have sought to discover why protection retains such popular strength in spite of all exposures of its fallacies; to trace the connection between the tariff question and those still more important social questions, now rapidly becoming the “burning questions” of our times; and to show to what radical measures the principle of free trade logically leads. While pointing out the falsity of the belief that tariffs can protect labor, I have not failed to recognize the facts which give this belief vitality, and, by an examination of these facts, have shown, not only how little the working classes can hope from that mere “revenue reform” which is miscalled “free trade,” but how much they have to hope from real free trade. By thus harmonizing the truths which free traders perceive with the facts that to protectionists make their own theory plausible, I believe I have opened ground upon which those separated by seemingly irreconcilable differences of opinion may unite for that full application of the free-trade principle which would secure both the largest production and the fairest distribution of wealth….
