I doubt if anyone would argue that a world wide asset bubble created the financial crisis, the worst component of which was residential mortgage abuse.
Inferior and fraudulent RMBS's and bad servicer practices were the essential problem of the economy in 2009 and remain so today. The banks have an incentive to foreclose instead of modify loans, but consumers have learned how to fight foreclosures. When foreclosure inventory is still overhanging the market, consumers are smart enough to know we haven't hit bottom on prices, so they hold off on purchases. Loan modifications haven't worked very well, but the issue goes back to bank incentives, not to mention continued fraudulent practices.
The lack of a housing industry rebound is the single biggest factor in high unemployment. No less than Buffet has said that when new housing starts get up into the range of a million units a year, unemployment will drop to 7%. The log jam in foreclosures and the disincentives of banks to modify loans are helping to keep the economy in limbo.
