Geeks have turned out to be some of the most ruthless capitalists around. A few years ago the new economy was a wide-open frontier. Today it is dominated by a handful of tightly held oligopolies. Google and Apple provide over 90% of the operating systems for smartphones. Facebook counts more than half of North Americans and Europeans as its customers. The lords of cyberspace have done everything possible to reduce their earthly costs. They employ remarkably few people: with a market cap of $290 billion Google is about six times bigger than GM but employs only around a fifth as many workers. At the same time the tech tycoons have displayed a banker-like enthusiasm for hoovering up public subsidies and then avoiding taxes. The American government laid the foundations of the tech revolution by investing heavily in the creation of everything from the internet to digital personal assistants. But tech giants have structured their businesses so that they give as little back as possible.
