"...but unwanted by whom?

The curious point is that the hopeful one concludes by saying, "When people have large families and small wages, not only is there a high infantile death-rate, but often those who do live to grow up are stunted and weakened by having had to share the family income for a time with those who died early. There would be less unhappiness if there were no unwanted children." You will observe that he tacitly takes it for granted that the small wages and the income, desperately shared, are the fixed points, like day and night, the conditions of human life. Compared with them marriage and maternity are luxuries, things to be modified to suit the wage market. There are unwanted children; but unwanted by whom?...He means that the employers do not want to pay [the parents] properly. Doubtless, if you said to him directly, "Are you in favour of low wages?" he would say, "No." But I am not, in this chapter, talking about the effect on such modern minds of a cross-examination to which they do not subject themselves. I am talking about the way their minds work, the instinctive trick and turn of their thoughts, the things they assume before argument, and the way they faintly feel that the world is going. And, frankly, the turn of their mind is to tell the child he is not wanted, as the turn of my mind is to tell the profiteer he is not wanted. Motherhood, they feel, and a full childhood, and the beauty of brothers and sisters, are good things in their way, but not so good as a bad wage. About the mutilation of womanhood and the massacre of men unborn, he signs himself "Hopeful." He is hopeful of female indignity, hopeful of human annihilation. But about improving the small bad wage he signs himself "Hopeless."
