Now that Trump is president, looks like it's starting to decline again.
That's not even considering the issues of planning, permits, installing machines, training workers, etc, in a more down to earth facility like a generic food plant, or heck forbid something seriously regulated (I hope) like making prescription drugs.
That real impact from investment may be 5-10+ years from the initial funding allocation.
Your billion dollar factory can start returning the investment years earlier when you manufacture elsewhere.
It's those last two, impact on the commons and unfair worker treatment, that are examples of where I _would_ support reasonable tariffs. Particularly if funds from those tariffs went to remediating the impact and were agreed to (also observed) by a majority of other leading countries / economic blocks.
It is about manufacturing jobs as identity and social status. Biden would create manufacturing as a "modern factories that create things". These do not employ all that many people and wont revert the world back to idealized past.
Production of critical parts within allied or the same nation is a reasonable goal.
It's probably also more energy efficient to manufacture things closer and ship less.
"a hard working guy can't get ahead any more because xyz"
It is ironic there are many very hard working guys in China, Philipines, Vietnam ...

>"But the more I study the White Death of the past two decades, the more I am instead reminded of the tragic trajectory of a now much less publicized American race, Native Americans. Like American Indians, working-class white Americans seem to be living, and dying, like a defeated people, quietly offing themselves with so little to-do that nobody even noticed what was happening to working-class white lifespans for the first fifteen years of this century."
Speaking more concretely: Canadians are willing to suffer more pain today (vis-à-vis America) than before because of the trade war.

So, being charitable with the OP, I can see how you might say that conservatives in the US believe that the US's declining status in manufacturing created a world in which "a hard working guy can't get ahead any more because everything is made in China", and thus a perception that in order to create equity and dignity we have to return to internal self reliance, ala juche or autarky.
