No use arguing with Nocturne really, Kiddo. He is writing from within a school of thought he's very competent in and seems to have read books upon books which both support and oppose his views (based on INTPc discussions about economics previously under a different nick). And yes he can be arrogant at times, but it's always with a dimpled smile.
My point is that you'd have to throw books upon books at him to persuade him, and he'd answer with even more books, and even the experts fling books at each other and tear each others tiny tufts of gray hair over this issue, so it won't be resolved in a thread on MBTIc. For all I know he might be right, but as a history major writing from within a rather different school of thought, I have my doubts. Seems to me like the same problem the communist ideal had. Pretty on paper, doesn't work because it's ultimately dealing with people, not machines. (But then again the current economic system seems rather doomed in the long run as well, so it might be an improvement even if it's not ideal).
