The Dow Jones : Gold Ratio Static Since 1928

Not so long ago there was a massive buzz online around Ron Paul and his libertarian financial policies, one of which was his aim to move away from the current Fiat system back towards gold. It’s a good idea, if not a little ambitious. It would mean that my pension would actually be worth something! I wonder why Mr. Paul would think of this chart showing the ratio in value of the Dow Jones : Gold is the same today as it was in 1928.
