From Andrew Hacker’s piece on tech workers in the 9 July 2015 New York Review:
Contrary to such alarmist demands [from Obama et al that we need to add more STEM (science, technology, engineering, and math) graduates], Falling Behind? makes a convincing case that even now the US has all the high-tech brains and bodies it needs, or at least that the economy can absorb. Teitelbaum points out that “US higher education routinely awards more degrees in science and engineering than can be employed in science and engineering occupations.” Recent reports reinforce his claim. A 2014 study by the National Science Board found that of 19.5 million holders of degrees in science, technology, engineering, and mathematics, only 5.4 million were working in those fields, and a good question is what they do instead. The Center for Economic Policy and Research, tracing graduates from 2010 through 2014, discovered that 28 percent of engineers and 38 percent of computer sciencetists [sic!] were either unemployed or holding jobs that did not need their training.
