Ernest Crosby on intellectual versus manual labor

From Ernest Crosby's Neighbor and Labor:

"In deciding between the merits of labor with the hand or with the head, we must remember that as society is now organized a very large share of intellectual work is devoted to the task of outwitting competitors, of speculating in values, of securing and protecting unjust privileges and of reaping their fruits, and that a comparatively small proportion is of any direct benefit to the masses of the people."
