Henry Kissinger: 'Today's economy, by contrast, contains at least 20 significant trading nations of widely different cultural backgrounds with great variations in labor costs and standard of living. In such conditions, competition becomes more ruthless. Nearly all industrial democracies – even while they give lip service to the ideals of free trade – have sought to nudge the terms of trade in a nationalist direction. Subsidies of exports, non-tariff barriers to import, guaranteed credits, as well as the manipulation of exchange rates become the order of the day.'
