The trade-offs with trade are a little more complex than that. For example, if foreign steel was super cheap, you could have the people previously working in steel work in construction, and build more buildings. Or if midwestern auto manufacturing jobs were middle-class due to unions, but the economy shifts to services like Amazon, there is no inherent reason why service jobs couldn’t also be unionized.
In principle it’s not that different from automation - you can think of either as a black box you put money in and get product out. If you are playing your other cards right (admittedly a big if) it would be possible to largely benefit from either.
Traditionally they’ve been worried about inflation but they’ve overestimated that most of the past decade (although it’s jumped up recently in response to the massive short term Covid spending). I don’t think the new stuff being proposed, while large, is nearly as high on a yearly basis so hopefully it can hit a non-inflationary sweet spot (although who knows).
One concrete thing I would 100% advocate though, which I guess is an example of a "nuanced" strategy as you alluded to:
Gimp / legislate away white-labelling of foreign products and drop shipping-like businesses. These have had a huge "spam" effect on products and consumer's brand-awareness that it'd be so worth it. It's made people unable to discern quality which is a huge win for places like China that at the bottom-end of the price spectrum simply don't have the quality we expect and would usually want to avoid by virtue of paying more.
