Then don't! The politicians are depending on that!
In a more serious vein, I don't know what this author is thinking with the pollyanna ending. If the world monetary system collapses how does he expect to build a new one? We have heard the myth of the Phoenix rising from the ashes, we saw Europe rebuilt after WWII, the world survived the Great Depression but in those cases there was always a winner still standing. If the dollar collapses so does everything else, as the author points out.
How do you reflate the balloon after all the air is gone? Oil, gold, land, etc. all will still have value but with no accepted money how will transactions take place? No one can carry barrels of oil around with them, or the deeds to their property, or pounds of gold to exchange, in a world of varying values.
Without an accepted medium of exchange nothing moves.
The aristocrats will hole up in their mansions and ride it out.
:) Pretty good advice. Thanks!
