A sudden stop would have a bigger effect that just losing money.
The pandemic already showed that.
This can only be solved in the long run and not in the short term.
But I doubt that will happen because this wouldn't need questioning the principles of capitalism.
Totalitarianism and capitalism always worked well together.
The most totalitarian states were the most anti-capitalist.
Capitalism means tolerating the emergence of independent centers of economic power, which is a threat to totalitarian control. That is why the PRC has been arresting wealthy tech founder-CEOs in China.
Cheap labor is easier to get in totalitarian states, that's why China is the workbench of the world and that's why the FRG let produce in the GDR and even gave it credits so that the production could continue.
I think you're technically right, but what you're implying is not. States following all kinds of economic systems work well together. For example, Venezuela works well with Russia and China, and is a fully socialist state.
And while you are right about capitalist states benefiting from the cheap labor of totalitarian states, capitalist states benefit even more from the capital skilled work forces from other capitalist states.
I'm sure the CIA would be surprised to hear that.
