At the end of the 20th century, it took 43 ounces of gold to buy the Dow stocks.

Well, as of yesterday, you could have bought the Dow for only 15 ounces....

Mogambo sez: I suggest that you take the time to buy some
gold bullion, silver bullion and some oil stocks, and
when I get back you can tell me all about how much money
you made...

Gold, which is the only widely accepted means of exchange that cannot be destabilised by man, will adjust in price
to reflect disorder in man-made money. When  the Fifth monetary Phase occurs,  the recent bull market in Gold will
prove to be only the beginning.  In these circumstances, investors in Gold would stand to profit handsomely.
