First, it will have to make up its mind as to how many people we want in the country. If we want less than at present, we must ascertain how many less; and if we allow the reduction to be made by the continued operation of the present sterilization of marriage, we must settle how the process is to be stopped when it has gone far enough. But if we desire to maintain the population at its present figure, or to increase it, we must take immediate steps to induce people of moderate means to marry earlier and to have more children. There is less urgency in the case of the very poor and the very rich. They breed recklessly: the rich because they can afford it, and the poor because they cannot afford the precautions by which the artisans and the middle classes avoid big families. Nevertheless the population declines, because the high birth rate of the very poor is counterbalanced by a huge infantile-mortality in the slums, whilst the very rich are also the very few, and are becoming sterilized by the spreading revolt of their women against excessive childbearing--sometimes against any childbearing.
This last cause is important. It cannot be removed by any economic readjustment. If every family were provided with 10,000 pounds a year tomorrow, women would still refuse more and more to continue bearing children until they are exhausted whilst numbers of others are bearing no children at all. Even if every woman bearing and rearing a valuable child received a handsome series of payments, thereby making motherhood a real profession as it ought to be, the number of women able or willing to give more of their lives to gestation and nursing than three or four children would cost them might not be very large if the advance in social organization and conscience indicated by such payments involved also the opening up of other means of livelihood to women. And it must be remembered that urban civilization itself, insofar as it is a method of evolution (and when it is not this, it is simply a nuisance), is a sterilizing process as far as numbers go. It is harder to keep up the supply of elephants than of sparrows and rabbits; and for the same reason it will be harder to keep up the supply of highly cultivated men and women than it now is of agricultural laborers. Bees get out of this difficulty by a special system of feeding which enables a queen bee to produce 4,000 eggs a day whilst the other females lose their sex altogether and become workers supporting the males in luxury and idleness until the queen has found her mate, when the queen kills him and the quondam females kill all the rest (such at least are the accounts given by romantic naturalists of the matter).
