Of course, but even if Americans were willing to do that kind of work for those wages it wouldn't have much impact. The kind of manufacturing that makes serious money doesn't and usually can't use cheap labour, not in the long run at least. And in those parts of the economy where cheap labour is effective, agriculture for instance, the availability of cheap immigrant labour is simply holding back innovation.

But the US is a major manufacturing nation anyway. US manufacturing output is more than half of that of China while having only a quarter of the population.

When groups like the far right say bring back manufacturing they are just posturing to those voters who have been disadvantaged by changes in the commercial landscape that reduces the number of unskilled and semi-skilled jobs. If they really cared about those people they would support massive improvements to education and training so that at least the next generation had a chance rather than idiotic schemes to 'bring back' the kinds of work that no one needs.
