A gold bug site.. still..

“As a reserve currency there is an extra demand for the dollar.. We may see a run.. illiquid capital moves.. or Capital Outflow where the dollar falls and real assets fall.  Not unlike what has been seen in third world economy’s.”

Still there are problems without addressing the trade imbalance. 

So, “it’s complicated.. with no real robust.. easy answers.”
