British Pizza Chain To Install Cones of Silence 122

itwbennett writes "British pizza chain Pizza Express is installing iPod docks and soundproof domes in booths of their new iPizzeria stores. 'The idea is that you can plug in your iPod and play whatever music you like without disturbing other diners,' says blogger Peter Smith. 'But I'm sure it'd work for talking about government secrets and other spy stuff, too.'"

You are correct that economics is not a zero-sum game. Investors pay money to buy stock in a company, and that company tries to create value for its shareholders. If they succeed, then it's a positive-sum game for the shareholders, employees, and customers. When enough companies create value, then the economy grows, and the economy is a positive-sum game.

However, this article is not talking about the economy as a whole, or about investing, but about high-frequency trading. And trading is a zero-sum game. Value is not created in the 40-milliseconds between trades, and for everyone who makes money trading, someone else is losing money.

There's a good explanation of this in an article by Henry Blodget.
