The act of 1842, by the excessive rates of duty which it imposed on many articles, either totally excluded them from importation or greatly reduced the amount imported, and thus diminished instead of producing revenue. By it the taxes were imposed not for the legitimate purpose of raising revenue, but to afford advantages to favored classes at the expense of a large majority of their fellow-citizens. Those employed in agriculture, mechanical pursuits, commerce, and navigation were compelled to contribute from their substance to swell the profits and overgrown wealth of the comparatively few who had invested their capital in manufactures. The taxes were not levied in proportion to the value of the articles upon which they were imposed, but, widely departing from this just rule, the lighter taxes were in many cases levied upon articles of luxury and high price and the heavier taxes on those of necessity and low price, consumed by the great mass of the people. It was a system the inevitable effect of which was to relieve favored classes and the wealthy few from contributing their just proportion for the support of Government, and to lay the burden on the labor of the many engaged in other pursuits than manufactures. A system so unequal and unjust has been superseded by the existing law, which imposes duties not for the benefit or injury of classes or pursuits, but distributes and, as far as practicable, equalizes the public burdens among all classes and occupations. The favored classes who under the unequal and unjust system which has been repealed have heretofore realized large profits, and many of them amassed large fortunes at the expense of the many who have been made tributary to them, will have no reason to complain if they shall be required to bear their just proportion of the taxes necessary for the support of Government. So far from it, it will be perceived by an examination of the existing law that discriminations in the rates of duty imposed within the revenue principle have been retained in their favor. The incidental aid against foreign competition which they still enjoy gives them an advantage which no other pursuits possess, but of this none others will complain, because the duties levied are necessary for revenue. These revenue duties, including freights and charges, which the importer must pay before he can come in competition with the home manufacturer in our markets, amount on nearly all our leading branches of manufacture to more than one-third of the value of the imported article, and in some cases to almost one-half its value. With such advantages it is not doubted that our domestic manufacturers will continue to prosper, realizing in well-conducted establishments even greater profits than can be derived from any other regular business. Indeed, so far from requiring the protection of even incidental revenue duties, our manufacturers in several leading branches are extending
