Oddly enough, the triffin dilemma is sort of a larger version of the mortgage crisis in the US.  The banks knew that their debtors could not pay them back, and yet in the short term the loans were still mutually beneficial.  The banks got a mortgage agreement, that could be used as a cash like asset, and the debtor got a house, which he had no intention of paying for.  Until it exploded it looked great for everyone, because the debtor assumed the house would go up in value and he could sell it for a profit at any time, and the banks assumed the debt was backed by the value of the house, which would increase anyway.  The inflation of housing prices due to the fraudulent creation of money (creation of debt is creation of money in the current system), led the asset (housing) to form bubble that popped, and now the entire world is paying the price for what was, in essence, a giant counterfeiting scheme.
