Trump’s message is very powerful.
A lot of working people have seen their jobs offshored for years while politicians from both sides told us to just deal with it.
Biden (and GWB too for that matter), when asked about this issue said some devious politician spin like “we have nothing to fear from China” or “we can’t have a policy based on fear”.
I think it’s perfectly legit to fear your industry being decimated and your skills obsolete.
