Motherhood must not be financially insecure, because this would defeat its eugenic purpose. Society, therefore, as a matter of self-preservation, must ensure to woman her mental and economic security. Civilization's margin is large enough to provide this. We spend large amounts on luxuries and evils which are contrary to the genesis of self-preservation, while motherhood is its basic necessity. When public opinion is educated in the essentials of eugenics much of this can be, and will be diverted to a nobler purpose. The total cost necessary to ensure the adequate care of dependent [19] motherhood would be a mere fraction of the national expenditure, and not a tithe of what we spend in pension allowances yearly. The latter is regarded as an honorable debt and is at best the direct product of a decadent ideal, while motherhood constitutes the very germ of the only altruistic idealism for all the future. We concede, therefore, that the children and the mothers must be provided for, not only as a product of the true construction of the ethics of sociology, but in obedience to the fundamental law of a moral system of eugenics. We must go further and assert that children must be cared for through the mother. It has been the practice to divorce the improvident mother from her dependent children. This has been demonstrated to be not only an altruistic fallacy. It has proved to be an economic blunder. There is another type of evil which largely menaces the eugenic ideal of motherhood. It is those cases where married women who have children are compelled to be the bread winners of the family as well as its mothers. No woman can earn support for herself and children outside of her home and competently assume the responsibilities of motherhood at the same time. Whatever aid a mother renders to the state, as a result of effort in factory or shop, is of infinitely less value, from an economic standpoint, than her contribution as mother in caring for her own children in her own home. A careful study of infant mortality, and the conditions of child life, so far as survival value is concerned, condemns in the strongest and most vital sense this whole practice. The preservation of the race is the essential requisite, and it is the vital industry of any people. Any seeming economic necessity which destroys that industry is one that will contribute largely to the downfall of the people as a race.
