Many people are inclined to dismiss Donald Trump. He’s bombastic, prone to lies and clearly unprepared. But no one should dismiss the concerns of the people of Paris, Kentucky, one of many communities devastated by the fall of the coal economy.

Condescension — often the vernacular of political elites and the media — simply reinforces their grievances. It will be a difficult road, but the next president must take decisive steps to mend America’s class divide.
