This from a very perceptive essay by Daniel Rodgers:

More realistically, liberals must find ways to win back some of those who swung to Donald Trump’s camp. Populists, the press routinely calls them. But aside from their distrust of distant experts and cosmopolitan elites, Trump’s core voters have little in common politically with the People’s Party of the American 1890s. The 1890s Populists, like today’s Trump supporters, sometimes fell for terribly oversimplified answers. But the Populists hurled their political fury at the forces of organized money: the bankers, the monopolists, the railroad magnates, and the politicians who wrote the back-room deals of the money-men into law. The conviction that powers Trump voters’ imaginations is just the reverse. Theirs is a world in which not capitalist institutions but the political establishment hogs the seats of power. In their minds, government rigs the game for its own advantages, tying up the potential expansive force of business with rules that only serve to keep the regulators in jobs and the poor as their clients. Only through this story is it possible to redirect anger at plant closings from the corporations who order them to the liberal establishment that is said to be covertly responsible.
