But a leading nation, a nation upon which all depend not only in this country but around the world, cannot afford to be satisfied, to look back or to pause. On our strength and growth depend the strength of others, the spread of free world trade and unity, and continued confidence in our leadership and our currency. The underdeveloped countries are dependent upon us for the sale of their primary commodities and for aid to their struggling economies. In short, a prosperous and growing America is important not only to Americans--it is, as the spokesman for 20 Western nations in the Organization for Economic Cooperation and Development, as he stressed this week, of vital importance to the entire Western World.
