There are so many underlying changes to the established relationship between Labor and Capital in the US that would be a necessary part of keeping jobs here that it would effectively make us a completely different country. For example -- suppose one could snap one's fingers and "bring back" millions of manufacturing jobs. What would lead one to conclude those would be the kind of "good jobs" everyone is envisioning?…
Manufacturing in particular... it's very easy for folks to say we should bring those jobs back to the US but people are often shocked when confronted with the prices of items manufactured in the US. I don't say that to dismiss the thought but it would be a lot more difficult for folks to swallow than they think it would be.
In practice, not sure. But it's not like the prices dropped drastically when mfg. was outsourced, the companies pocketed a most of the savings as profit.
