Mr. Obama is still president but he's got less than two months left in office.  The future or at least the next four years belong to Mr. Trump and the rest of the world and even the media knows this now.  As for diplomatic events blowing up before he goes I'm quite sure that the US government has had over 200 years dealing with foreign governments attempting to take advantage of the two month transition period in the hope that a certain level of inertia exists to slow down reaction times.

As regards the notion of millionaires and billionaires running the country so what else is new?  Perhaps you've forgotten the Kennedys (billionaires in 2010 dollars) or Roosevelts (both branches).  Going back even further George Washington had a wealth of $515 million in 2010 dollars, Jefferson $212 million, Jackson $119 million and James Madison $101 million.  Even Bernie Sanders is a millionaire.
