An other link to a thread from here:http://uselectionatlas.org/FORUM/index.php?topic=93611.0
It's a video that shows how worked the modern economic system until know. I found it pretty interesting. I tend to trust the video but I'm not an expert to say if the demonstration in it is really honest, if so that's kinda amazing. As no one posted a comment to contradict the talk of the video, maybe it shows the actual working of the system.
Well, the video is about 50 mins long but personally I stayed, the first 1/4 tells about the history of economy and the rest is on the modern system and it's perspectives.
