“No amount of force will break an egg-shell if exerted on one side alone. So capital could not squeeze labor as long as labor was free to natural opportunities, and in a world where these natural materials and opportunities were as free to all as is the air to us, there could be no difficulty in finding employment, no willing hands conjoined with hungry stomachs, no tendency of wages toward the minimum on which the worker could barely live. In such a world we would no more think of thanking anybody for furnishing us employment than we here think of thanking anybody for furnishing us with appetites.
That the Creator might have put us in the kind of world I have sought to imagine, as readily as in this kind of a world, I have no doubt. Why he has not done so may, however, I think, be seen. That kind of a world would be best for fools. This is the best for men who will use the intelligence with which they have been gifted. Of this, however, I shall speak hereafter. What I am now trying to do by asking my readers to endeavor to imagine a world in which natural opportunities were "as free as air," is to show that the barrier which prevents labor from freely using land is the nether millstone against which labor is ground, the true cause of the difficulties which are apparent through the whole industrial organization.”
