From: RTAmerica | Sep 6, 2011Wall Street fell for a third straight day on worries that Europe can't take care of its debt dilemma. Many Europeans are trading in their euros for Swiss francs. Now the Swiss National Bank has put a minimum exchange rate of 1.20 francs to the euro. The reason is the present value of the franc is a danger to the financial system. The SNB said it would implement the minimum rate by buying foreign currency in unlimited quantities. Paul Craig Roberts, former Reagan administration official and columnist, tells us how this could affect the world economy.
