The behaviour that caused the mortgage bubble and financial crisis of 2008 was a natural outcome and continuation of this pattern, rather than some kind of economic accident.

This behaviour is criminal. We are talking about deliberate concealment of financial transactions that aided terrorism, nuclear weapons proliferation and large-scale tax evasion; assisting in major financial frauds and in concealment of criminal assets; and committing frauds that substantially worsened the worst financial bubbles and crises since the Depression.

And yet none of this conduct has been punished in any significant way.
