Peter Joseph in Berlin: Economic Calculation in a Natural Law / Resource-Based Economy
Peter Joseph gave this address at a Zeitgeist Movement event in Berlin, Germany recently. This is a long one, coming in at two hours at 45 minutes, but it is well worth your time. The address, as the title indicates, focuses upon the issue of economic calculation--one of the consistent complains from the Anarcho-Capitalists--and how it works in a world that's run on a resource-based economy.
