Matt Ridley explains how the human race is able to create things that a single human being could not possibly create, how we are all dependent on each other, and the reason we have tripled our average real wealth per person on earth even with the population growth that we have had.
This speech explains exactly why capitalism and free trade is in the blood of humans, and why people fighting against it or restraining it in any form are nothing but evil.
