I take no pleasure in seeing anyone lose a job, but I can’t say that the recent headlines showing that America’s biggest banks have been losing money on their trading operations, and are having to radically shrink as a result, are entirely bad news for the country. Over the last decade, America’s banking sector got pumped up by steroids — in the form of cheap credit and leverage — every bit as much as Major League Baseball’s home run hitters. And if one result of the downsizing of Wall Street is that more of America’s best and brightest math and physics students decide to go into science and real engineering rather than financial engineering, the country will be a whole lot better off.
Why? Because, to paraphrase the Columbia University economist Jagdish Bhagwati, Wall Street, which was originally designed to finance “creative destruction” (the creation of new industries and products to replace old ones), fell into the habit in the last decade of financing too much “destructive creation” (inventing leveraged financial products with no more societal value than betting on whether Lindy’s sold more cheesecake than strudel). When those products blew up, they almost took the whole economy with them.
I was on Wall Street two weeks ago, and I’ve been in Silicon Valley this past week. What a contrast! While Wall Street is being rattled by a social revolution, Silicon Valley is being by transformed by another technology revolution — one that is taking the world from connected to hyperconnected and individuals from empowered to superempowered. It is the biggest leap forward in the I.T. revolution since the mainframe computer was replaced by desktops and the Web. It is going to change everything about how companies and societies operate.
