In terms of the country's overall health I think you could argue we've sold industrial capacity for wealth, and it's too early to say if it was a good trade. Reliance on China for Rare Earth Minerals is commonly referenced, [1] but China is in general a major supplier to the DoW, which negatively hampers our ability to for example credibly deter an invasion of Taiwan. Arguably Post WWII Pax Americana, which relies on industrial capacity, has kept the peace more so than economic interdependence. For example Pre WWI Germany and the UK were each others' largest trading partner, and a conflict was argued to be economically unthinkable. [2]

It also increases the immiseration of those in the areas replaced[3], which is likely a contributor to rising populism and political instability. Most of this malaise is just hidden in places like the Rust Belt.
