April 11, 2015 NYT by Paul Krugman — Way back in 1996, on the 100th anniversary of the New York Times magazine, the Times had a clever idea: they asked a number of people to write essays pretending to look backward a century from the perspective of 2096.
Sadly, most of the writers were too uptight and dignified to comply; they wrote blah-blah-the-decades-to-come stuff. But I threw myself in with a little piece titled White Collars Turn Blue.
As the title suggested, one theme of the essay was a pushback against the notion that advancing technology would mean ever-growing demand for highly educated workers; I argued that computers would take over many of the cognitive tasks we find difficult, but that human beings would continue to be wanted for jobs that require common sense, including many forms of manual labor.
Or as one friend described it at the time, my thesis was that we’ll always need maids and gardeners.
And it’s happening. I missed this paper by Beaudry, Green, and Sand when it was first circulated, but it’s right on that issue:
[W]e argue that in about the year 2000, the demand for skill (or, more specifically, for cognitive tasks often associated with high educational skill) underwent a reversal. Many researchers have documented a strong, ongoing increase in the demand for skills in the decades leading up to 2000. In this paper, we document a decline in that demand in the years since 2000, even as the supply of high education workers continues to grow. We go on to show that, in response to this demand reversal, high-skilled workers have moved down the occupational ladder and have begun to perform jobs traditionally performed by lower-skilled workers.
An obvious implication is that belief that income inequality is all about, and can be fixed by, education is even more wrong than you thought.
