It is at once obvious that superior families will rarely encounter this problem. The parents will, by their superior earning capacity and the exercise of thrift and foresight, have provided for the wants of their old age. A superior man will therefore seldom be under economic pressure to limit the number of his own children because of the necessity of supporting his parents. In inferior families, on the other hand, the parents will have made no adequate provision for their old age. A son will have to assume their support, and thus reduce the number of his own children,--a eugenic result. With old age pensions from the state, the economic pressure would be taken off these inferior families and the children would thus be encouraged to marry earlier and have more children,--a dysgenic result. From this point of view, the most eugenic course would perhaps be to make the support of parents by children compulsory, in cases where any support was needed. Such a step would not handicap superior families, but would hold back the inferior. A contributory system of old age pensions, for which the money was provided out of the individual's earnings, and laid aside for his old age, would also be satisfactory. A system which led to the payment of old age pensions by the state would be harmful. The latter system would be evil in still another way because, as is the case with most social legislation of this type, the funds for carrying out such a scheme must naturally be furnished by the efficient members of the community. This adds to their financial burdens and encourages the young men to postpone marriage longer and to have fewer children when they do marry,--a dysgenic result. It appears, therefore, that old age pensions paid by the state would be dysgenic in a number of ways, encouraging the increase of the inferior part of the population at the expense of the superior. If old age pensions are necessary, they should be contributory. THE SEX HYGIENE MOVEMENT Sexual morality is thought by some to be substantially synonymous with eugenics or to be included by it. One of the authors has protested previously[184] against this confusion of the meaning of the word "eugenics." The fallacy of believing that a campaign against sexual immorality is a campaign for eugenics will be apparent if the proposition is analyzed. First, does sexual immorality increase or decrease the marriage rate of the offenders? We conclude that it reduces the marriage rate. Although it is true that some individuals might by sexual experience become so awakened as to be less satisfied with a continent life, and might thus in some cases be led to marriage, yet this is more than counterbalanced by the following considerations: 1. The mere consciousness of loss of virginity has led in some sensitive persons, especially women, to an unwillingness to marry from a sense of unworthiness. This is not common, yet such cases are known.
