The man at the top of the intellectual pyramid contributes the most to all those below him, but gets nothing except his material payment, receiving no intellectual bonus from others to add to the value of his time. The man at the bottom who, left to himself, would starve in his hopeless ineptitude, contributes nothing to those above him, but receives the bonus of all of their brains. Such is the nature of the ‘competition’ between the strong and the weak of the intellect. Such is the pattern of ‘exploitation’ for which you have damned the strong.
