The State, through its individual citizens, has a primary right to obtain the particular commodity which it happens to prefer, without restrictions imposed for the benefit of any particular tradesman. We find instead that the ordinary purchaser no longer has any effective, or selective, demand. He has to buy what he is given. The informal organisation of the Trust system, primarily a financial operation,[24] has involved the whole market in a network of interdependent industries. The sale of the finished product is controlled and restricted by the vendors of the raw material. Corn is imported by shipbuilders; ships are built by iron merchants; iron furnaces are controlled by coal owners, and coal mines are secured by money-lenders. The system of the tied house, originally an indigenous corruption of the liquor trade, is being extended to every industry in the land. We can no longer buy the bread we like, but have to eat whatever by-product least interferes with the miller's profits. The consumer's loss of any power of effective demand would not necessarily be of national importance, if at least there were any guarantee that the unique commodity offered by the average trust system were genuine and of good quality. One of the State's most elementary rights is that of ensuring to its citizens a pure supply of elementary commodities. Yet Commerce has taken no steps, even in its own interests, to suppress the horrid arts of adulteration, in which the motives of the thief usurp the methods of the poisoner, with results which may be inferred from the meagre chronicles of the analyst.[25] Education is the life of the State.[26] It is therefore of the gravest importance that Commerce should in no circumstances whatever be allowed to interfere with the education of the future citizens. Yet, before the war, in spite of the legislation of the last fifty years,[27] no less than a quarter of a million children of school age were exempted from school attendance for employment in various occupations.[28] Even apart from such improper exemptions the "School Age" fixed by law in itself gives quite insufficient protection. The brain of a girl hardly begins to wake up, or take any natural interest in the acquisition of general ideas, before she comes to puberty. But all over London girls of thirteen or fourteen leave school and are sent by their mothers to earn half a crown a week matching patterns or sewing on sequins.
