"The results which have been obtained in the United States, by the application of machinery wherever it has been practicable to manufactures, are rendered still more remarkable by the fact that combinations to resist its introduction there are unheard of. The workmen hail with satisfaction all mechanical improvements, the importance and value of which, as releasing them from the drudgery of unskilled labour, they are enabled by education to understand and appreciate. With the comparatively superabundant supply of hands in this country, and therefore a proportionate difficulty in obtaining remunerative employment, the working classes have less sympathy with the progress of invention. Their condition is a less favourable one than that of their American brethren for forming a just and unprejudiced estimate of the influence which the introduction of machinery is calculated to exercise on their state and prospects. I cannot resist the conclusion, however, that the different views taken by our operatives and those of the United States upon this subject are determined by other and powerful causes, besides those dependent on the supply of labour in the two countries. The principles which ought to regulate the relations between the employer and the employed seem to be thoroughly understood and appreciated in the United States; and while the law of limited liability affords the most ample facilities for the investment of capital in business, the intelligent and educated artisan is left equally free to earn all that he can, by making the best use of his hands, without let or hindrance by his fellows."[4] Without attempting to give this volume the formal shape of a treatise on Political Economy, it is the wish of the author to convey the broad parts of his subject in a somewhat desultory manner, but one which is not altogether devoid of logical arrangement. He desires especially to be understood by _the young_; for upon their right appreciation of the principles which govern society will depend much of the security and happiness of our own and the coming time. The danger of our present period of transition is, that theory should expect too much, and that practice should do too little, in the amelioration of the condition of the people. A great number of woodcuts have been for the first time introduced into this volume, which illustrate mechanical inventions. But the author begs distinctly to be understood that his object here is not to _describe_ processes. His notices of them, more or less extended, are simply to illustrate the course of his argument; and in that way to make the book more useful, because more attractive, for purposes of education.
