One thing that a lot of folks here at FR forget; as the Japanese say, "Business is war."
When China has the lion's share of world industry and the jobs and taxes that go with them, their economy will prosper.
When the United States loses most of it's industry, and the jobs and taxes that go with it, our economy will wither.
One wonders: When the United States loses our heavy manufacturing capacity, who will produce the equipment that would be needed to support a war effort on the scale of WWII?
Oh, right, I forgot- that can never, ever happen.
You identify some things that I've wondered a lot myself.
