Greenspan: Gold is "Primary Global Currency"

``"Today, going back on to the gold standard would be perceived as an act of desperation. But if the gold standard were in place today we would not have reached the situation in which we now find ourselves. We cannot afford to spend on infrastructure in the way that we should. The US sorely needs it, and it would pay for itself eventually in the form of a better economic environment (infrastructure). But few of such benefits would be reflected in private cash flow to repay debt. ''
