Bigger even than the dot com crash and the Tulip bubble of the 1600’s when tulip bulbs were selling for $1,000 each and crashed 99% in one year in 1635!” Says New York Times best selling author and one of the world’s leading economic forecasters Harry Dent who has arrived in Australia for a national tour.  He joined Peter Switzer for On The Money to discuss this and his new book Zero Hour.
