Steel (and Aluminum) tariffs, cheap way to get vote in a very few states, but do economic damage to rest of country. It seems the idea of steel tariffs have existed as long as the industrial revolution, longer than America was a country, was quickly used soon after establishment of America, and had its first big use in America just after the Civil War. But the fickle political winds and lack of planning is what hurt America. In short: Steel producing regions became lazy, failed to update manufacturing equipment, eventually lost out to cheaper or better foreign steel products. Those updates also include using less manpower to produce the same steel. Concurrently new materials, mainly plastics, have replaced large demand for steel. Just like coal, technology and demand had caused loss of jobs, and nothing #45 or Republicans can do will bring it back. Yet some states still yearn for the gleaming days of shiny hard steel, and irrationally demand restoration of forever lost jobs. Still, the future of politics rests on how the next political leaders recycle the rust belt into new industries. PS: one can say WW2 set up a situation that 71 year later #45 was able to tap into and turn 3 key states for him. A direct impact from of the results of WW2.
