"The Greenspan era has nurtured a vast financial sector. All the people in this business need something to do. Since they invest other people's money, they are biased toward bullish sentiment. Otherwise, if they say it's all bad, their investors will take back the money, and they will lose their jobs. Governments know that, and create noise to give them excuses to be bullish.
This institutional weakness has been a catastrophe for people who trust investment professionals. In the past two decades, equity investors have done worse than those who held U.S. market bonds, and who lost big in Japan and emerging markets in general. It is astonishing that a value-destroying industry has lasted so long. The greater irony is that salaries in this industry have been two to three times above what's paid in other sector."
