Agree with this take.  (and not attributing what follows to you, Michael.) 

This economy works fabulously well for a minority at the top.  Obama's complacent assessment of the economy he left Trump--attaboy, Barack--reflects the obliviousness of many politicians and elites to the experiences of the great many in our country (and how can this be heard by those not flourishing while also hearing Obama say during his presidency that inequality is the biggest problem we face?) 

Every time a politician gloats about this economy it just reinforces and amplifies the "politicians out of touch" narrative, always in the background and more salient these days.  It appears lost on those glowing about this economy that prosperity remains mostly unshared (true for decades now), that we have historically high inequality and a perception in many quarters of a more rigged than usual economy continuously enriching unaccountable holders of special privileges and having nothing to do with a reward for merit and legitimate accomplishment, piled on top of too few living wage jobs with decent benefits,  diminishing economic expectations, and many communities in transparent deep distress with no hope evident on the horizon. 

Praising this economy and more of the same economic globalization is heard by many as indifference and a vote for a status quo that, hello, news flash, is not at all satisfactory to a majority these days.  Trying to point out to people that you know their reality (stop complaining, this economy is good or as good as can be attained, get real, life is great, be happy with what you have) and are the more perceptive and educated interpreter of it than they are is not in my estimation a promising strategy for electoral success and interrupting the disturbing dynamics and trends.  It only feeds a sense that the system is unresponsive and not up to the challenges we are facing, and that those elites supporting the status quo are indifferent or worse to the plight of their fellow citizens who are dealing as best they can with hard times and little help or even concern from what they might at one time have thought of as their government.  

Right wing media has done a masterful job of portraying the "coastal elites" as liberal and Democratic rather than corporate Republican as well.  You know the endlessly repeated narrative: the coastal Democratic elites do not have a clue what life is like for many ordinary people in this country, are unsympathetic, and, worse, sometimes appear to presume that those struggling in our society are not too sharp, a bunch of racist and sexist rubes, or both.  A response to the latter is sometimes "look in the f'ing mirror!".  This dynamic mirrors the resentments of some in the South during the civil rights struggles towards those in the North who, they felt, looked down their noses at their handling of race relations and general presumed stupidity and backwardness. 

I'd say this cultural disconnect is on full display here as elsewhere.
