In all lands, men whose toil creates abounding wealth are pinched with poverty, and, while advancing civilization opens wider vistas and awakens new desires, are held down to brutish levels by animal needs. Bitterly conscious of injustice, feeling in their inmost souls that they were made for more than so narrow a life, they, too, spasmodically struggle and cry out. But until they trace effect to cause, until they see how they are fettered and how they may be freed, their struggles and outcries are as vain as those of the bull. Nay, they are vainer. I shall go out and drive the bull in the way that will untwist his rope. But who shall drive men into freedom? Till they use the reason with which they have been gifted, nothing can avail. For them there is no special providence.
— Henry George, Protection or Free Trade
