$US as a reserve currency is fading. It happened to the british pound. the air in the balloon is being led out slowly until the big whoosh happens ie an overnite devaluation. it happened at 20% to the BP.
Just like the former Soviet Union before its collapse.... once the economy and culture are "fully socialized", the economy slows to a crawl (or worse) and everybody is equal... THEY ALL HAVE NOTHING! (except government, of course)
Do you mean gold or oil? Either way, you're right. Cuba isn't exactly Saudi Arabia or S. Africa and I'm sure they don't have their own Ft. Knox after decades of Castro-ism.
