In 1980, the Republicans won the game: they were able to start dismantling liberalism, tearing apart the New Deal, destroying unions, sending the good jobs overseas, and sending all the economic gains to the rich rather than to the whole population. So it’s a bit provoking when conservative pundits offer this story that the Democrats abandoned the working class.
It’s true that Trump has appealed to economic anxiety— among other things. But his very framing of the issue shows that he doesn’t understand the issues or have any notion on how to solve them. He talks as if the problem is foreigners— either Mexicans coming to this country to steal jobs, or Chinese somehow taking advantage of us by selling us cheap things. He isn’t running for President of Mexico or China, so he can’t actually do anything about either problem, nor would building walls (whether made of bricks or tariffs) actually re-create manufacturing jobs.
