Every 40 years or so the US defaults, the US coming off the gold standard in 1971 was one of the US great defaults and the US should have defaulted during the 2008 crisis, they didn't and now the crisis is going to be so much deeper.
This is why China, Russia and India are buying up huge reserves of gold, China is one of the largest miners but not sellers, they are keeping it all at home; they all know what's coming. The US economy needs to add several dollars of debt for every dollar of growth because they have exported their manufacturing base away, they have exported their money making ability and all this is at record low interest rates.
What's going to happen when interest rates rise? They can't balance the books at 0% how are they going to do it at 3% or 5%? I am going long Popcorn as this unfolds over the next few years, it's going to be fun to watch.
