>Political discourse and behavior have become highly polarized, and what I like to call the ‘honest middle’ cannot be heard above the din. People often blame the economic policies of ‘the other side’ or they belligerently snipe at foreign competition. But we are failing to understand why we are failing. All of these problems have a single, little-noticed root cause: We have been living off low-hanging fruit for at least three hundred years. We have built social and economic institutions on the expectation of a lot of low-hanging fruit, but that fruit is mostly gone.
In a figurative sense, the American economy has enjoyed lots of low-hanging fruit since at least the seventeenth century, whether it be free land, lots of immigrant labor, or powerful new technologies. Yet during the last forty years, that low-hanging fruit started disappearing, and we started pretending it was still there. We have failed to recognize that we are at a technological plateau and the trees are barer than we would like to think. That’s it. That is what has gone wrong.
