Nevertheless, under the conditions of life in the modern city, and especially since the Industrial Revolution and the employment of masses of women and men at wages that always tend to gravitate toward a minimum, it is impossible for many to save and also to rear families, while intemperance and vice always furnish their quota to the classes that outlive their serviceable years in dire poverty and, as old age advances, become increasingly dependent not only for subsistence but also for personal care. There are still a few students of the social and economic questions here involved who urge that all the aged, even the latter group, should, if possible, be cared for in their own homes by their children and grandchildren and that to remove them to institutions, public or private, not only robs them of interest in life but weakens filial piety and is detrimental to the interests of the family and to the instincts upon which it rests. They urge that all children owe to all parents this return for the care that was bestowed on them during their early, helpless years and that such ministrations are essential for a true and complete home, etc. But even if we grant all this, there still remain the childless old and poor who are alone in the world. There are also the vicious, toward whom their children, with too much reason, feel that they owe nothing, that their own very existence was due to the accidents of passion, and that they were not only unwelcome guests but were made the victims of cruelty, want, etc. Then there are the sick who cannot be properly cared for at home and each additional mouth always means less food for all the rest.
