I think that people in the Rust Belt have legitimate concerns.  I read and found JD Vance's Hillbilly Elegy very good.  Another good book about this is The Unwinding.  I also think that many don't have a very expansive worldview and are casually racist.  People keep forgetting I am not some liberal snob.  Some people I grew up with don't have the most enlightened views on women and minorities.  Trump tapped into and appealed to these people's unfounded fears and prejudices.  He didn't give them detailed policy procedures to bring jobs to the Midwest. 

And I am not a fan of the GOP's policies; it annoys me that the GOP keeps pretending this is the 1980s.  However, I think that Trump's election actually sets back reform conservatism.  Trumpism is basically Heritage economics mixed with racial demagoguery and him being an indispensible demigod.
