The King of Wall Street!
Interestingly, when J.P. Morgan died, Frank Vanderlip, the President of National City Bank (i.e., Citi Bank), wrote: "The king is dead, but there are no cries of 'Long live the king' for the general verdict seems to be that there will be no other king; that Mr. Morgan can have no successor."
Respectfully, the esteemed Mr. Vanderlip was wrong. Jamie D is the King... the Sun King no less!
