This article in the Guardian is interesting:  https://www.theguardian.com/us-news/2016/nov/09/white-voters-victory-donald-trump-exit-polls.  It tends to debunk the idea that Trump voters were those who feel left behind by globalization.  Apparently, Trump was elected by many white folks, a good number of whom make more than $50,000 per year.  These voters include extended family  members who are white, who are financially comfortable,some better educated than others, but all who long for a mythical past, when "all was right with the world".  They are also all, to some extent, bigoted. They include people with whom I had conversations, pre-election, who informed me that it was a documented fact that Hillary was a national security concern.  
There is nothing about Trump's history that would lead anyone to believe that he would actually change things for the better for those with fewer advantages.
