For much of human history, what we now call “privacy” was better known as being rich. Privacy, like wealth, was something that most people had little or none of. Farmers, slaves and serfs resided in simple dwellings, usually with other people, sometimes even sharing space with animals. They had no expectation that a meaningful part of their lives would be unwatchable or otherwise off limits to others. That would have required homes with private rooms. And only rich people had those.
The spread of mass privacy, surely one of modern civilization’s more impressive achievements, thus depended on another, even more impressive achievement: the creation of a middle class. Only over the past 300 years or so, as increasingly large numbers of people gained the means to control their physical environment through the acquisition of wealth and private property, did privacy norms and eventually privacy rights come into existence. What is a right to privacy without a room of your own?
The historical link between privacy and the forces of wealth creation helps explain why privacy is under siege today. It reminds us, first, that mass privacy is not a basic feature of human existence but a byproduct of a specific economic arrangement — and therefore a contingent and impermanent state of affairs. And it reminds us, second, that in a capitalist country, our baseline of privacy depends on where the money is. And today that has changed.
The forces of wealth creation no longer favor the expansion of privacy but work to undermine it. We have witnessed the rise of what I call “attention merchants” and what the sociologist Shoshana Zuboff calls “surveillance capitalism” — the commodification of our personal databy tech giants like Facebook and Google and their imitators in telecommunications, electronics and other industries. We face a future in which active surveillance is such a routine part of business that for most people it is nearly inescapable. In this respect, we are on the road back to serfdom.
