Wall Street’s Dead End

By FELIX SALMON

THE stock market has been big news in recent days. Last week’s report that Deutsche Börse, a giant German exchange, intends to buy the New York Stock Exchange, creating a company worth some $24 billion, arrived shortly after the Dow broke the 12,000-point barrier for the first time since before the financial crisis.

These developments drew headlines because they seemed to exemplify significant trends in the American economy. But look at America’s stock exchanges more closely, and there’s less to them than meets the eye. In truth, the stock market is becoming increasingly irrelevant — a trend that threatens the core principles of American capitalism.
