'Another Great Depression is all but inevitable’ - that's the view of Steve Keen. No wonder he's been called the ‘Merchant of Gloom’.

But then Keen is one of the few economists to have predicted the global financial crisis.

His way of avoiding depression? Write off the debt, bankrupt the banks, nationalize the financial system, and start all over again.
