economic and (what is still more important) intellectual resources.
In the case of these domestic manufactures, the comparative cost of production, on which the interchange between countries depends, is much lower than in proportion to the quantity of labor employed. The work-people, looking to the earnings of their loom for a part only, if for any part, of their actual maintenance, can afford to work for a less remuneration than the lowest rate of wages which can permanently exist in the employments by which the laborer has to support the whole expense of a family. Working, as they do, not for an employer but for themselves, they may be said to carry on the manufacture at no cost at all, except the small expense of a loom and of the material; and the limit of possible cheapness is not the necessity of living by their trade, but that of earning enough by the work to make that social employment of their leisure hours not disagreeable.
§ 4. —But not when common to All.
These two cases, of slave-labor and of domestic [pg 461] manufactures, exemplify the conditions under which low wages enable a country to sell its commodities cheaper in foreign markets, and consequently to undersell its rivals, or to avoid being undersold by them. But no such advantage is conferred by low wages when common to all branches of industry. General low wages never caused any country to undersell its rivals, nor did general high wages ever hinder it from doing so.
To demonstrate this, we must turn to an elementary principle which was discussed in a former chapter.290 General low wages do not cause low prices, nor high wages high prices, within the country itself. General prices are not raised by a rise of wages, any more than they would be raised by an increase of the quantity of labor required in all production. Expenses which affect all commodities equally have no influence on prices. If the maker of broadcloth or cutlery, and nobody else, had to pay
