Boris Johnson makes the case for global free trade

This country is leaving its chrysalis.  We are reemerging after decades of hibernation as a campaigner for global free trade.  And frankly it is not a moment too soon.  Because the argument for this fundamental liberty is now not being made.  We in the global community are in danger of forgetting the insights of those great Scottish thinkers: the invisible hand of Adam Smith, and of course David Ricardo's more subtle, but indispensable, principle of comparative advantage, which teaches that if countries learn to specialize and exchange, then overall wealth will increase and productivity will increase, leading [Richard] Cobden to conclude that,

free trade is God's diplomacy, the only certain way of uniting people in the bonds of peace, since the more freely goods borders, the less likely it is that troops will ever cross borders.

And since these notions were born here in this country, it has been free trade that has done more than any other single economic idea to raise billions out of poverty and incredibly fast.
