I agree with your assessment.  What we actually have is a corporate oligarchy and unfortunately, Trump is turning out to be as much a corporatist as he is anything else.  For all his blather about HRC and Goldman Sachs, he is turning his administration into a front for GS and essentially promoting GS from major lobbyists to the writers and deciders of major economic initiatives.

One of the points being missed in political commentary about the 'great political divide' in this country is that both so called populist movements, right and left, have defined the same common problem... the outsized influence of mega corporate/individual money in how this country is managed.  Trump's supporters opted for the 'wealthy independent businessman can fix it' mantra and Bernie supporters more or less opted for the 'responsive government can fix it' solution.   The corporate oligarchy continues unless both movements concentrate on the problem instead of being divided by their preferred solutions.
