But in addition to this general cause of delusion and error, which pervades all states really regulated by the popular voice, there is another and a still more powerful one which occasions and perpetuates the most ruinous public delusions in an advanced and complicated state of society. This arises from the strength and influence of the classes who become interested in the perpetuating of error because they profit by it, and the impossibility of getting the great bulk of men to see, among the numerous causes which are then acting upon their fortunes, the _real ones_ to which their sufferings are owing. They know perfectly when they are prosperous, and when unfortunate; but they do not know, and cannot be brought to see, to what either the prosperity or adversity is to be ascribed. If the consequences of a particular line of policy could be brought before them by a _clear and short_ process of demonstration--if they could see from whence their suffering in truth comes, and the arrow, known to have been discharged from the quivers of Free Trade and a metallic currency, could be seen festering in the breast of every industrious man in the country, one universal burst of indignation would arise from one end of the kingdom to the other. This system, so profitable to the moneyed rich, so ruinous to the industrious poor, would be abolished, amidst shouts of congratulation from one end of the country to the other, in a month. But they cannot be brought to see this; and the vast riches which the continuance of this system is daily bringing to the moneyed classes, enables them to perpetuate the darkness.
