John Kenneth Galbraith Quote

A man who is hungry need never be told of his need for food. If he is inspired by his appetite, he is immune to the influence of Messrs. Batten, Barton, Durstine & Osborn. The latter are effective only with those who are so far removed from physical want that they do not already know what they want.
