This guy seems to not understand business with his "intelligent markets" premise. For example, I sell sheds (to parallel his ice cream example). What I know as a businessman is that if I don't sell enough sheds, its not because people don't have money for them. Its because I haven't found enough people who have the money. They're out there. I just kick in a few advertising dollars, put up an incentive on my website to close the sale, and boom! I'm successful. Does this mean that I outsmarted a null market?
