The globalized economy has demonstrated that a single country and supply the majority of the world's manufacturing needs, at least for a while.
Taiwan creates most of the worlds semiconductors. China makes the majority of everything else. Silicon Valley created a majority of the tech market's value.
But there's a cap where the world has enough stuff at least in the short term, and growth slows.
Humans only need a certain amount to survive. With populations leveling out, industry will shift from servicing human needs, to the needs of corporations and other industries. Consumers will become a minority in the future economy.
What will corporations value in the future, that they're willing to spend on recurring human capital expenses? I think the answer will always be: the tasks that will help companies grow.
