Education for the Third Industrial Revolution

At the risk of sounding like a crass economist, I want to assert at the outset that one major purpose of the K-12 educational system is vocational in the broad sense. Specifically, the K-12 system is a mechanism for preparing cadres of 18-year-olds (many of whom will get some higher education first) to perform the tasks needed and remunerated by the U.S. job market (or of being easily trained to do so). To be sure, this narrowly economic purpose of mass public education is not the only reason to educate America's youth; an educated citizenry presumably has other social benefits as well. But I believe it is an important purpose and, in any case, it is the perspective that guides this essay. Any reader who does not accept this initial premise can stop reading right now. My second, and much more controversial, premise is that the needs of the U.S. economy are changing (that's not the controversial part) in ways that are at least somewhat predictable (that is the controversial part). To be sure, I am not foolish enough to believe that we can predict in detail the mix of jobs that will be available in the United States in, say, 2028 or 2038 and then fine-tune the educational system to meet those demands. But I think at least two broad trends are clearly foreseeable.
