As the companies, workers and wealth of Silicon Valley creep north into the city of San Francisco, the effects of an industry with a relatively small but highly paid labor force are leading to widespread social unrest. Embodied in the symbolic protests around “Google Buses,” lower-income residents are reacting to tech’s ability to produce so much wealth that is thinly distributed to a small labor force, disinvested from  local infrastructure (with private transportation), and funneled to comically useless purposes like the “Google Barges” mysteriously floating in the Bay. However, conversations about tech wealth are often limited to its distribution—with even mainstream economists (as well as The Economist) conceding that, “Facebook will never need more than a few thousand employees.” Clearly, the other side of this is production; even with its relatively small labor force, Facebook can generate billions in wealth and profits. Instagram, the hip photo sharing mobile application, famously had only 13 employees when it sold for $1 billion (that’s around $77 million per employee).
