That&#x27;s some unrealistic criteria you have there.  No one is an expert in every facet of physics or maths.  Yes economists specialize.  As do engineers.  Or doctors.<p>As for pundits, there&#x27;s a reason they&#x27;re pundits...  Is Sergey Brin or John Carmack going to host a tech segment on TV?  That&#x27;s silly, as silly as thinking TV economists would be as successful as people like Jan Hatzius (BTW, he did correctly anticipate the crisis of 2008, and GS bet against the market and made a killing during that time).
