After Katrina there were tours of the devastated Ninth Ward. So it makes a kind of twisted sense that, according to Andrew Clark in the Guardian, tourists can now take a guided tour through the financial crisis on Wall Street.
According to Clark the tours, including one called The Wall Street Experience, feature such highlights as looking at an ACTUAL Collateralised Debt Obligation (or CDO) and a goodish amount of righteous outrage at the financial excesses of AIG.
The Wall Street Experience is run by a former Deutsche Bank trader called Andrew Luan who now charges $50 to show you some buildings downtown. He seems to have learned something from his time on the Street.
