Trump did decent in the rust belt. Many of them have lost their good paying manufacturing jobs. If, and this is a big if, we can bring back manufacturing in the US they can get their jobs back.
What is the time scale we are talking about when we talk about this change?
What plan has Trump put in place to built the infrastructure needed for this? What funding available to businesses? Oh none you say.
If I'm company leadership, I'm not doing anything but trying to limit damage while this guy's in office. His tariffs can turn on a dime- his petulance is business poison.
