To these folks, you're telling them that their kids are forbidden from earning a living the way that they did. That's not a tough sell, it's a non starter. They believe that their way of life is being attacked and has been taken from them. And a lot of them understand just enough to know that it's been / is being driven by politicians. So, essentially, it's being done by the same people who they would also be told to trust with their futures.
That's rough.
None, that's what I'm getting at. These areas are in a long term terminal decline and there is no fixing it. It's an international economic trend, nothing US politicians do will make a difference.

The best you can do is manage the decline, anyone promising anything more is lying. All the last 4 years have done is squander the power they have as a political block, this is also waning.
