Normally the man of great productive capacity who becomes rich by guiding the labor of many other men does so by enabling them to produce more than they could produce without his guidance

Context

“In our industrial and social system the interests of all men are so closely intertwined that in the immense majority of cases a straight-dealing man who by his efficiency, by his ingenuity and industry, benefits himself must also benefit others. Normally the man of great productive capacity who becomes rich by guiding the labor of many other men does so by enabling them to produce more than they could produce without his guidance; and both he and they share in the benefit, which comes also to the public at large. The superficial fact that the sharing may be unequal must never blind us to the underlying fact that there is this sharing, and that the benefit comes in some degree to each man concerned.” source
