…from a 4/14/14 column… tis rich, mis amigos…Michael Lewis starts his best-selling new book “Flash Boys,” a polemic against high-frequency trading, with the story of the Spread Networks tunnel.
And that’s part of a much broader picture, in which society is devoting an ever-growing share of its resources to financial wheeling and dealing, while getting little or nothing in return.
How much waste are we talking about? A paper by Thomas Philipponof New York University puts it at several hundred billion dollars a year.
Mr. Philippon starts with the familiar observation that finance has grown much faster than the economy as a whole. Specifically, the share of G.D.P. accruing to bankers, traders, and so on has nearly doubled since 1980, when we started dismantling the system of financial regulation created as a response to the Great Depression.
In short, we’re giving huge sums to the financial industry while receiving little or nothing — maybe less than nothing — in return. Mr. Philippon puts the waste at 2 percent of G.D.P. Yet even that figure, I’d argue, understates the true cost of our bloated financial industry. For there is a clear correlation between the rise of modern finance and America’s return to Gilded Age levels of inequality.
