(21,786 posts)It was caused by something else entirely. Bubble markets don't happen because of mass fraud, they happen because of collective behaviour in driving up house prices (in this case it was historically low interest rates combined with deregulation in banking that allowed commercial banks to function as investment banks, and the packaging of mortgage loans into derivative securities).
And further, the 2007-08 mortgage crisis (and the economic crisis that accompanied it) wasn't caused by "mass fraud", either. What caused it? One thing. Oil prices, which hit $140 a barrel at their peak--conventional oil production peaked c. 2004-05, demand didn't slacken, the inexorable law of supply and demand saw the price steadily increase. A lot of people with subprime mortgages (by definition the riskiest loans) suddenly found themselves faced with a decision: put gas in the tank to get to work, and put food on the table (food and other commodity prices also rising because of oil prices) or pay the mortgage....which led to widespread defaults and the writedown on mortgage-backed securities.
