Adam Smith, in his great work, 'The Wealth of Nations,' says, "The property which every man has in his own labour, as it is the original foundation of all other property, so it is the most sacred and inviolable. The patrimony of a poor man lies in the strength and dexterity of his hands; and to hinder him from employing this strength and dexterity in what manner he thinks proper, without injury to his neighbour, is a plain violation of this most sacred property." The right of property, in general, has been defined by another writer, M. Say, to be "the exclusive faculty guaranteed to a man, or body of men, to dispose, at their own pleasure, of that which belongs to them." There can be no doubt that labour is entitled to the same protection as a property that capital is entitled to. There can be no doubt that the labourer has rights over his labour which no government and no individual should presume to interfere with. There can be no doubt that, as an exchanger of labour for capital, the labourer ought to be assured that the exchange shall in all respects be as free as the exchanges of any other description of property. His rights as an exchanger are, that he shall not be compelled to part with his property, by any arbitrary enactments, without having as ample an equivalent as the general laws of exchange will afford him; that he shall be free to use every just means, either by himself or by union with others, to obtain such an equivalent; that he shall be at full liberty to offer that property in the best market that he can find, without being limited to any particular market; that he may give to that property every modification which it is capable of receiving from his own natural or acquired skill, without being narrowed to any one form of producing it. In other words, natural justice demands that the working-man shall work when he please, and be idle when he please, always providing that, if he make a contract to work, he shall not violate that engagement by remaining idle; that no labour shall be forced from him, and no rate of payment for that labour prescribed by statutes or ordinances; that he shall be free to obtain as high wages as he can possibly get, and unite with others to obtain them, always providing that in his union he does not violate that freedom of industry in others which is the foundation of his own attempts to improve his condition; that he may go from place to place to exchange his labour without being interfered with by corporate rights or monopolies of any sort, whether of masters or workmen; and that he may turn from one employment to the other, if he so think fit, without being confined to the trade he originally learnt, or may strike into any line of employment without having regularly learnt it at all. When the working-man has these rights secured to him by the sanction of the laws, and the concurrence of the institutions and customs of the country in which he lives, he is in the condition of a free exchanger.
