It is seen that all countries of the same or similar economic structure reveal the identical conditions with regard to the distribution of the sexes according to ages. According thereto, and apart from all other causes already mentioned, a considerable number of women have in such countries no prospect of entering wedded life. The number of unmarried women is even still larger, because a large number of men prefer, for all sorts of reasons, to remain single. What say hereto those superficial folks, who oppose the endeavor of women after a more independent, equal-righted position in life, and who refer them to marriage and domestic life? The blame does not lie with the women that so many of them do not marry; and how matters stand with "conjugal happiness" has been sufficiently depicted. What becomes of the victims of our social conditions? The resentment of insulted and injured Nature expresses itself in the peculiar facial lines and characteristics whereby so-called old maids, the same as old ascetic bachelors, stamp themselves different from other human beings in all countries and all climates; and it gives testimony of the mighty and harmful effect of suppressed natural love. Nymphomania with women, and numerous kinds of hysteria, have their origin in that source; and also discontent in married life produces attacks of hysteria, and is responsible for barrenness. Such, in main outlines, is our modern married life and its effects. The conclusion is: _Modern marriage is an institution that is closely connected with the existing social condition, and stands or falls with it. But this marriage is in the course of dissolution and decay, exactly as capitalist society itself_,--because, as demonstrated under the several heads on the subject of marriage: 1. Relatively, the number of births declines, although population increases on the whole,--showing that the condition of the family deteriorates. 2. Actions for divorce increase in numbers, considerably more than does population, and, in the majority of cases, the plaintiffs are women, although, both economically and socially, they are the greatest sufferers thereunder,--showing that the unfavorable factors, that operate upon marriage, are on the increase, and marriage, accordingly, is dissolving and falling to pieces. 3. Relatively, the number of marriages is on the decline, although population increases,--showing again that marriage, in the eyes of many, no longer answers its social and moral purposes, and is considered worthless, or dangerous. 4. In almost all the countries of civilization there is a disproportion between the number of the sexes, and to the disadvantage of the female sex, and the disproportion is not caused by births--there are, on the average, more boys born than girls,--but is due to unfavorable social and political causes, that lie in the political and economic conditions.
