I was going to say to diversify locations - what if some virus is strong in the USA but is absent somewhere else?
I guess if there is true competition in the global economy, that will happen naturally. (France, China, Japan, etc. would all be making stuff).
But with China, when the government helps their companies, they have such an unfair advantage that they can take in 90+% of production of some items.
It’s still better for us to do more and be more self-sufficient here. Less waste and pollution with freight shipping. More biodiversity in agriculture. More security in times of emergency and flexibility in changing our own production as needed. And more low to moderate skill jobs for all lower-skill Americans we’ve created through our bad immigration policies of the last half century.
