Your whole post is spot on.
As for what happens on d-day? We will have a very weak dollar. That’s ok. In my lifetime Russia had a very weak Ruble. Brazil had a very weak Real. Both bounced back.
When you mentioned Goldman Sachs it reminded me of their current Enron ways. Google: Goldman Sachs aluminum Detroit.
Wherever there is a scheme or a bubble, you can usually find Goldman Sachs. Ever notice how so many of our Bureaucrats from both parties all come from Goldman Sachs?
There is a long history of debacles in the USA, but somehow Goldman always seems to come out on top.
