The free market is not failing. Current markets that are failing are hardly "free." What is failing is a system of government regulation and control that supports wall street and the rich at the expense of the middle class.
The governments and their federal banks created every single problem called out in the article. To turn around, blame free-markets, and propose more government as the solution is disgustingly disingenuous.
The IMF itself is not a proponent of the free market. It exists precisely to support excess government spending and to bail rich bondholders who make donations to politicians. Nothing lassiez faire about that.
The laissez faire solution to an overspending government would be bondholders losing money, currency depreciating, and poor leaders being held accountable - to which the IMF is diametrically opposed.
