Unfortunately, all those service jobs which have become the backbone of our economy depend totally on physical objects, which are manufactured somewhere. It would be better if that somewhere were here.
I'de say that depends on the product being manufactured.
People complained about mechanical production replacing human labor, but in the long run it meant products were manufactured more efficiently at a lower cost resulting a higher standard of living for all.
So what if the slave labor wages in China mean some low tech manufacturing jobs go there. It frees up Americans for better paying high tech jobs, and the low price China products raise our standard of living. Just like we had our own slaves.
