Those factory jobs are, to a first approximation, gone for good. Either they are being done by humans in other countries that not only have a cost of living less than 1/5 of ours, but also have massive supply and logistics chains built up to support them, or they have been automated. Sure, there will be a few much-ballyhooed factories built and staffed, but compared to the period after WWII, which is what most of them are thinking of, it's going to be less than a drop in the bucket.
And, for the vast majority of people, that's an unalloyed good. Factory jobs are hard on the body. Office work may have less of a nationalist mythos built up around it, but it's genuinely better for most people.
Or will someone explain that those jobs, too, are a thing of the past...
