As the world heads further down the road to trade protectionism and war, Mark takes a look at what Ludwig von Mises dubbed the "Montaigne Fallacy." This fallacy is based on the illogical idea that with voluntary exchange, one person's benefits come at the expense of the other, or what we call "zero sum thinking." Mark shows exactly why the idea is wrong and explains that Montaigne's other ideas are also wrongheaded.  Be sure to follow Minor Issues at Mises.org/MinorIssues.
