How this state of things has been brought about is shown by the steady diminution in the proportion of the population engaged in the work of production. Adam Smith cautioned his countrymen that "if the whole surplus produce of America in grain of all sorts, salt provisions, and fish," were "forced into the market of Great Britain," it would "interfere too much with the prosperity of our own people." He thought it would be a "great discouragement to agriculture." And yet, from that hour to the present, no effort has been spared to increase in all the nations of the world the surplus of raw produce, to be poured into the British market, and thus to produce competition between the producers abroad and the producers at home, to the manifest injury of both. The more the linen manufacture, or those of wool, hemp, or iron, could be discouraged abroad, the greater was the quantity of raw products to be sent to London and Liverpool, and the less the inducement for applying labour to the improvement of English land. For a time, this operation, so far as regarded food, was restrained by the corn-laws; but now the whole system is precisely that which was reprobated by the most profound political economist that Britain has ever produced. Its consequences are seen in the following figures:--In 1811, the proportion of the population of England engaged in agriculture was 35 per cent. In 1841 it had fallen to 25 per cent., and now it can scarcely exceed 22 per cent., and even in 1841 the actual number was less than it had been thirty years before.[143] Thus driven out from the land, Englishmen had to seek other employment, while the same system was annually driving to England tens of thousands of the poor people of Scotland and Ireland; and thus forced competition for the sale in England of the raw products of the earth produced competition there for the sale of labour; the result of which is seen in the fact that agricultural wages have been from 6s. to 9s. a week, and the labourer has become from year to year more a slave to the caprices of his employer, whether the great farmer or the wealthy owner of mills or furnaces. The total population of the _United Kingdom_ dependent upon agriculture cannot be taken at more than ten millions; and as agricultural wages cannot be estimated at a higher average than 5s. per week, there cannot be, including the earnings of women, more than 6s. per family; and if that be divided among four, it gives 1s. 6d. per head, or £3 18s. per annum, and a total amount, to be divided among ten millions of people, of 40 millions of pounds, or 192 millions of dollars. In reflecting upon this, the reader is requested to bear in mind that it provides wages for every week in the year, whereas throughout a considerable portion of the United Kingdom very much of the time is unoccupied.
