Brooks always does a great job of presenting a very complex topic in a very simple to understand manner. Essentially, he is discussing the role the government should play in facilitating a free market. Is it a free market if the government facilitates it? I say so, and as much as I believe in Ann Rand style objectivisim when panic and irrational behavior positions to do deep economic damage the government should take steps to bring everyone back to reality.
In Brook's words:
We do seem to have reached some Bernanke-era consensus. In normal times, the free market works well. But in a crisis like this one, few are willing to sit back and let the market find its own equilibrium.
