Thank you so much to Drs. George Selgin and Tm Harford. They have put the nonsense of the “buy local” mantra into terms almost anyone can understand.
Here it is in a nutshell.
When country A enacts a blockade or economic sanctions against country B, does country B become more prosperous or less? Does country B thank country A for the good fortune of being forced to “buy local,” or does it claim that country A has committed an act of war?
Free Banking – The Folly that is “Local” Currency: “More importantly, the object that the local currency movement would achieve if it could—that of of “keeping trade within the community”–is, like all forms of protectionism, a highly dubious one: As Tim Harford succinctly puts it, “the gains from more trade with locals are more than offset by the losses from less trade with strangers. Otherwise economic sanctions would be a blessing.” (Try telling a Palestinian or Cuban about the virtues of “buying local”!)”
