" The majority of any society comprised, Smith knew, not landlords or merchants, but "servants, laborers, and workmen of different kinds," who derived their income from wages. Their welfare was the prime concern of economic policy, as Smith conceived it. "No society can surely be flourishing and happy, of which the far greater part of the members are poor and miserable," he wrote. "It is but equity, besides, that they who feed, clothe and lodge the whole body of the people should have such a share of the produce of their own labour as to be themselves tolerably well fed, clothed, and lodged." The chief economic concern of the legislator, in Smith's view, ought to be the purchasing power of wages, since that was the measure of the material well-being of the bulk of the population.
