The effect of these various factors in the increasing cost of children is to decrease fecundity not so much on the basis of income of parents, as on the basis of their standards. The prudent, conscientious parent is therefore the one most affected, and the reduction in births is greatest in that class, where eugenics is most loth to see it. The remedy appears to be a change in public opinion which will result in a truer idea of values. Some readjustments in family budgets are called for, which will discriminate more clearly between expenditure that is worth while, and that which is not. Without depriving his children of the best medical attention and education, one may eliminate those invidious sources of expense which benefit neither the children nor anyone else,--overdressing, for instance. A simplification of life would not only enable superior people to have larger families, but would often be an advantage to the children already born. On the other hand, the fact that higher standards in a population lead to fewer children suggests a valuable means of reducing the birth-rate of the inferior. Raise their low standards of living and they will reduce their own fertility voluntarily (the birth control movement furnishing them with the possibility). All educational work in the slums therefore is likely to have a valuable though indirect eugenic outcome. The poor foreign-speaking areas in large cities, where immigrants live huddled together in squalor, should be broken up. As these people are given new ideas of comfort, and as their children are educated in American ways of living, there is every reason to expect a decline in their birth-rate, similar to that which has taken place among the native-born during the past generation. This elevation of standards in the lower classes will be accomplished without any particular exertion from eugenists; there are many agencies at work in this field, although they rarely realize the result of their work which we have just pointed out.
