“If plants, and live stock as well, require space and air, sunlight and love, children need them even more. The only real wealth of our country lies in the men and women of the next generation. A farmer would rather produce a thousand thoroughbreds than a million runts. How are we to breed a race of human thoroughbreds unless we follow the same plan? We must make this country into a garden of children instead of a disorderly back lot overrun with human weeds. In a home where there are too many children in proportion to the living space, the air and sunlight, the children are usually overcrowded and underfed. They are a constant burden on their mother's overtaxed strength and the father's earning capacity. Such homes cannot be gardens in any sense of the word.”
