Is the Global Dollar in Jeopardy?

The federal government has a real problem.   All the rescaling we need will be happening at once and I doubt we have the intellectual capacity to deal with the issues, especially after 40 years of fraudulent 'This time is different'.

Even with mostly a shut down problem in the Swamp, the central bank can continue run the reserve currency. But we have to make the shut downs more efficient.  I dunno.  Most likely technology will always be there to support ta liquid global dollar. I would be thinking about what other currencies we can use domestically is the dollar is reserved for global use.
