I heard this TED talk on the subject and it's really a call to action to start thinking about it, I don't think he proposed a solution. I read through the comments and it's the same old arguments, I think the idea posted on this site resolves them so I'm going to try to send something to this presenter. Also, in the comments I found a reference to a site that is trying to propose something very interesting. It wants to transfer ownership of corporations to universities. Obviously if they went to the trouble of making a website and a white paper and a video they think it's a good idea. I'll definitely get in touch with them to see what they think of my idea.
To recap my idea, it's just people joining forces, one at a time making better decisions. Choosing companies that are good for the long run not just the cheapest price today. If these companies end up being cooperatives, cool, if not, doesn't matter. This is the capitalism we're all striving for today, the market economy we want. The thing holding us back is an economy where the producers of goods are focusing on making us make bad decisions, because it is a more profitable business model in the short term. Check out the site or let me know if you want me to elaborate.
