we all hear that everyday; "this time its different" . anyway,i was listening to asome guy who runs a fund and he said usually a recession is cause by the fed raising rates but this time the fed was not raising and rates were very low by historical standads. this was cause by a steep decline in housing and mortgage related debt as well as a tightening of credit. we all know this already and it is certainly not anything new to us. however,real estate crash's and credit crunch's tend to weigh on the economy for long periods of time.
