Harry S Dent sees another bull run through this decade with the Dow perhaps reaching 35000, followed by the US economy sliding into a depression next decade after the baby boomers have passed their spending peak of ~47 years of age. The book that Harry Dent wrote in 1993 (during a recession) pretty well predicted everything that has happened in the economy over the last 9 years so based on the evidence I can see his economic modelling works extremely well.
