I don't know if this has been put out here before but this video is excellent. Here Paul Craig Roberts debates with Stefan Molyneux and he absolutely demolishes libertarian economics. Stefan in the end is left without an argument and so he just meekly says, 'we'll let the viewers decide.' As libertarianism is a cult, Stefan knows his devoted followers will say that he had won the debate.
Paul Craig Roberts has real experience but Stefan Molyneux just has pie in the sky magical thinking.
