The highest human attributes are perfectly compatible with the sex-relation, but not with the sexuo-economic relation. We see this opposition again in the tendency to collectivity in bodies of single men,—their comradeship, equality, and mutual helpfulness as compared with the attitude of the same men toward one another, when married. This is why the quality of “organizability” is stronger in men than in women; their common economic interests force them into relation, while the isolated and even antagonistic economic interests of women keep them from it. The condition of individual economic dependence in which women live resembles that of the savage in the forest. They obtain their economic goods by securing a male through their individual exertions, all competing freely to this end. No combination is possible. The numerous girls at a summer resort, in their attitude toward the scant supply of young men, bear an unconscious resemblance to the emulous savages in a too closely hunted forest. And here may be given an economic reason for the oft-noted bitterness with which the virtuous women regard the vicious. The virtuous woman stands in close ranks with her sisters, refusing to part with herself—her only economic goods—until she is assured of legal marriage, with its lifelong guarantee of support. Under equal proportions of birth in the two sexes, every woman would be tolerably sure of obtaining her demands. But here enters the vicious woman, and offers the same goods—though of inferior quality, to be sure—for a far less price. Every one of such illegitimate competitors lowers the chances of the unmarried women and the income of the married. No wonder those who hold themselves highly should be moved to bitterness at being undersold in this way. It is the hatred of the trade-unionist for “scab labor.” On the woman’s side we are steadily maintaining the force of primitive individual competition in the world as against the tendency of social progress to develope co-operation in its place, and this tendency of course is inherited by their sons. On the man’s side the same effect is produced through another feature of the relation. The tendency to individualism with sex-advantage is developed in man by an opposite process to that operating on the woman. She gets her living by getting a husband. He gets his wife by getting a living. It is to her individual economic advantage to secure a mate. It is to his individual sex-advantage to secure economic gain. The sex-functions to her have become economic functions. Economic functions to him have become sex-functions. This has confounded our natural economic competition, inevitably growing into economic co-operation, with the element of sex-competition,—an entirely different force.
