Why Friedrich Hayek Is Making a Comeback:With the failure of Keynesian stimulus, the late Austrian economist's ideas on state power and crony capitalism are getting a new hearing

The Wall Street Journal explains why Hayek is making a comeback:

First, he and fellow Austrian School economists such as Ludwig Von Mises argued that the economy is more complicated than the simple Keynesian story. Boosting aggregate demand by keeping school teachers employed will do little to help the construction workers and manufacturing workers who have borne the brunt of the current downturn. If those school teachers aren't buying more houses, construction workers are still going to take a while to find work. Keynesians like to claim that even digging holes and filling them is better than doing nothing because it gets money into the economy. But the main effect can be to raise the wages of ditch-diggers with limited effects outside that sector.

Second, Hayek highlighted the Fed's role in the business cycle. Former Fed Chairman Alan Greenspan's artificially low rates of 2002-2004 played a crucial role in inflating the housing bubble and distorting other investment decisions. Current monetary policy postpones the adjustments needed to heal the housing market.

Third, as Hayek contended in "The Road to Serfdom," political freedom and economic freedom are inextricably intertwined. In a centrally planned economy, the state inevitably infringes on what we do, what we enjoy, and where we live. When the state has the final say on the economy, the political opposition needs the permission of the state to act, speak and write. Economic control becomes political control.

Even when the state tries to steer only part of the economy in the name of the "public good," the power of the state corrupts those who wield that power. Hayek pointed out that powerful bureaucracies don't attract angels—they attract people who enjoy running the lives of others. They tend to take care of their friends before taking care of others. And they find increasing that power attractive. Crony capitalism shouldn't be confused with the real thing.
