Here's Peter Joseph speaking for an hour and three quarters in Berlin on 13 November (he needs to learn to be brief):
It's supposed to be on "economic calculation", but the first 30 minutes are an indictment of what he calls "market capitalism", the next 40 minutes on showing how we have the technology and resources to move on to a "post-scarcity" economy and society, and only the last 35 minutes on how the production and distribution of wealth could be organised without money, price or exchange (and it's very technical). Still, good stuff if you've got the patience.
