Rory Sutherland, the vice chairman of the legendary global advertising agency Ogilvy UK, may seem like an unlikely defender of capitalism, but he is one of its most persuasive and engaging.

Sutherland calls the stentorian Austrian economist Ludwig von Mises his hero and celebrates not capitalism's ruthless efficiency and capacity to outproduce a command economy but its ability to create seemingly trivial products such as Red Bull and to transform the disgusting-sounding Patagonian toothfish into the delicacy known as Chilean sea bass.
