The disaster as you put it started in 2007, and steadily got worse. Yes it really took off after obama was elected. You see election do have there consequences.
Plus the dot com bubble burst in early 2000.
Bush was the disaster. Two wars not included in any budget. Trillions in tax breaks that didn't do jack for the economy. Moving 2.4 million jobs to China. I just don't understand why Republicans ignore these fundamental causes.
I'm not arguing against Bush's "liberal" fiscal spending. However, let's not drop the buck at Bush's door. Every president in the last 70-80 years has involved our troops and/or monetary resources in conflicts overseas. Many (most) of them were unnecessary for our involvement. The U.S. foreign policy is what's too blame. I haven't seen much by any of the last 5 presidents do a damn thing to change our foreign policy....drastically that is.
