American collapse is gonna be a horror show because we are an economic parasite on the world, and collapse will be the host cutting off our proboscis. We cannot self-sustain.
Robert Reich once bragged that our economy was transforming into one where 20% of us would be well compensated "symbolic analysts" and everyone else would be servants to this class.
This is echoed in Primary Colors where Fake Clinton tells the shipbuilder union to get ready to go back to school because making things is over. We are all "symbolic analysts" now.
That's only possible because the rest of the world makes stuff for us to consume. On a net basis the world makes while we take. Capitalism is the international legal system which ensures this will happen through the enforcement of investor and property rights.
This is the "system of international rules" that Biden has warned China must be obeyed. Or else.
The world makes, we take (and pay in USD).
