Are the believers in so-called &quot;economic theory&quot; so desperate that they have to resort to name calling?<p>I sincerely hope someday you would read Blatt&#x27;s book with an open mind. It has <i>nothing</i> to do with Keen, and on few pages with a bit of matrix math he obtains far better model than economists with their supply and demand curves can ever hope. (In fact, John von Neumann apparently had fingers in it too - shame he didn&#x27;t live longer, we could have a proper economic theory today.)
