In consequence of present economic conditions it is possible to amass enormous wealth; but wants are still further increased relatively, which brings it about that frauds, embezzlements, etc., are often committed by persons of means, especially since the moral sentiments are lost when one thinks only of gaining money. But wealth is inconstant; he who has plenty today may be very poor tomorrow. This is what causes the disquiet and agitation that characterizes the bourgeoisie, and the neuroses that often follow. Finally the author dwells upon the work of women and children, so harmful to morality and to health. Alcoholism. The inevitable consequence of poverty is the abuse of alcoholic drinks. One who works too much and eats too little, who is badly housed and ill-clad, and has no intellectual occupation, finds in alcohol a means of forgetting his poverty. The life led by a great part of the bourgeoisie leads also to alcoholism. The harmful consequences of alcoholism are numerous, especially as regards criminality, because, first, it leads directly to violent crimes, and, secondly, it indirectly favors degeneracy. Fatherhood. It is only for economic reasons that legal marriage, its indissolubility, and all that belongs to it, are maintained. If each of the parents kept his or her economic independence, there would be no reason to take up the matter of legal regulation, and thus the question of whether the father of the child is or is not the legal husband of the mother would no longer concern the State. Prostitution. Most prostitutes come from the lower strata of society. Like the criminals they present signs of degeneracy, and from the sole fact of degeneracy have taken on larger proportions in the proletariat than in the other classes, though the chance that these women will recruit themselves in this class is already greater. The other causes of prostitution are of an economic nature, such as exploitation by parents, bad housing, etc. In consequence of prostitution syphilis spreads and in its turn favors degeneracy. Further, from the weakening of their moral sentiments prostitutes are more easily led to commit crimes. Ignorance. The cause of the great ignorance of the working-people—an important factor in criminality—is of an economic nature. The workers have to exhaust their strength, and have neither the leisure nor the means, for mental development.
