It is quite evident that the same alternative is not presented to Great Britain and Ireland, and that the united empire has ample means of increasing in wealth, population, and power, for a very long course of years, without being habitually dependent upon foreign supplies for the means of supporting its inhabitants. As we have clearly, therefore, our choice between two systems, under either of which we may certainly look forwards to a progressive increase of population and power; it remains for us to consider in which way the greatest portion of wealth and happiness may be steadily secured to the largest mass of the people. 1. And first let us look to the labouring classes of society, as the foundation on which the whole fabric rests; and, from their numbers, unquestionably of the greatest weight, in any estimate of national happiness. If I were convinced, that to open our ports, would be permanently to improve the condition of the labouring classes of society, I should consider the question as at once determined in favour of such a measure. But I own it appears to me, after the most deliberate attention to the subject, that it will be attended with effects very different from those of improvement. We are very apt to be deceived by names, and to be captivated with the idea of cheapness, without reflecting that the term is merely relative, and that it is very possible for a people to be miserably poor, and some of them starving, in a country where the money price of corn is very low. Of this the histories of Europe and Asia will afford abundant instances. In considering the condition of the lower classes of society, we must consider only the real exchangeable value of labour; that is, its power of commanding the necessaries, conveniences, and luxuries of life. I stated in the Observations, and more at large in the Inquiry into rents,(11*) that under the same demand for labour, and the same consequent power of purchasing the means of subsistence, a high money price of corn would give the labourer a very great advantage in the purchase of the conveniences and luxuries of life. The effect of this high money price would not, of course, be so marked among the very poorest of the society, and those who had the largest families; because so very great a part of their earnings must be employed in absolute necessaries. But to all those above the very poorest, the advantage of wages resulting from a price of eighty shillings a quarter for wheat, compared with fifty or sixty, would in the purchase of tea, sugar, cotton, linens, soap, candles, and many other articles, be such as to make their condition decidedly superior.
