The other day I found myself, as I often do, at a conference discussing lagging wages and soaring inequality. There was a lot of interesting discussion. But one thing that struck me was how many of the participants just assumed that robots are a big part of the problem — that machines are taking away the good jobs, or even jobs in general. For the most part this wasn’t even presented as a hypothesis, just as part of what everyone knows.

And this assumption has real implications for policy discussion. For example, a lot of the agitation for a universal basic income comes from the belief that jobs will become ever scarcer as the robot apocalypse overtakes the economy.

So it seems like a good idea to point out that in this case what everyone knows isn’t true. Predictions are hard, especially about the future, and maybe the robots really will come for all our jobs one of these days. But automation just isn’t a big part of the story of what happened to American workers over the past 40 years.

We do have a big problem — but it has very little to do with technology, and a lot to do with politics and power.
