As Nate Silver points out in this article, it's diificult to parse that scupulously as achievement in education is stongly tied to financial success in America. But it can be done and Trump's political strategy demonstrably did exactly that.

That's why Trump's catch phrase "Make America Great Again" worked so well- it evokes a sentimental memory of a dim past n which blue collar work paid quite well, in a world economy therwise in a post war shambles, manufacturing abroad greatly diminished with wrecked factories and infrastructure,

That world does not exist anymore. And, it can't be recreated by American isolationism. Sweatshop labor in 3rd world exonomies is morally reprehensible, but starvation in it's place is even less acceptable. Example- a pair of blue jeans made in America would cost $205 while using overseas workers makes them available for $60.

There's two ways to look at those facts- the quality of life made possible in America by employing and purchasinf products made by low cost foreign workers; and the improvement in the quality of life for those workers by selling to Americans. And the knowledge that a population gainfully employed in mutually profitable commercial exchange aren't likely to start wars.
