"It will be realized that the first need from the economic viewpoint, is that every nation and community shall be as self-supporting as possible; the second need is that there shall be no unemployment anywhere. It should be the duty of each nation, therefore, to discover and determine to what extent she can be self-supporting in the matter of food, without impoverishing her soil. This settled, she will secondly maintain full employment according to agreed standards, by the production of surplus goods or works of art for which she has especial genius or facilities."
