In a short and readable paper published through the Council on Foreign Relations’s “Renewing America” project, Thomas Hilliard makes some sensible recommendations about better training Americans for the “middle skill” jobs that the current trajectory of American industry is placing front and center, in both the manufacturing and service sectors.
Of course, whenever anyone tells you there’s a shortage of anything, if you believe in market-clearing mechanisms, you should be asking “at what price?” Companies complain they can’t find middle-skill workers, but don’t often put their money where their mouth is. Hilliard gets at this, but in an odd way. To me, the key paragraph in his essay is:
The middle-skills gap damages job creation and economic mobility. Employers are less likely to create good jobs with long-term advancement potential if the productivity of their workers does not cover their higher wages. A recent McKinsey study found that 86 percent of U.S. employers surveyed would pay more for a job candidate with the right training and hands-on-experience. . . In the absence of those skilled candidates, employers will compete on the basis of lower costs, a path that leads to outsourcing and widespread use of part-time and temporary workers.
While it’s true that productivity must support higher wages, I worry this gets the causation backwards. Maybe the issue is not the supply curve for labor but the demand curve. There’s a big gap between “would pay” in theory and “is offering cold, hard cash right now.” Actually, tracing back Hilliard’s reference, the McKinsey Center for Government goes on to say, “The actual likelihood of higher salaries clearly involves a broader range of factors, such as employer ability to pay and the degree of skills scarcity in the industry.”
In other words, the position of American industry on what they’re willing to pay for U.S. middle-skilled employees remains incoherent and unreliable, and as long as it is — and obviously so, to any thinking American — we’ll have continued trouble attracting either young people or adult learners into education and training curricula that produce the relevant skills.
The National Research Council has made available a pre-print of the forthcoming report of its Committee on The Mathematical Sciences in 2025, chaired by Caltech EE/applied physics professor Thomas Everhart. Like all NRC publications, it’s a long and dense document, but the summary remains fully accessible to the general reader. Though it makes all the usual pleas for funding of basic research without undue hope for immediate practical application, the report also starkly underlines what should now be obvious connections between mathematical knowledge and rapidly accumulating advances in a wide array of other disciplines and real-world applications. Even within mathematics itself, the report argues, boundaries between sub-disciplines are breaking down, and mathematicians who would formerly have seemed past their prime years of creativity can now still make important discoveries because it pays increasingly to have long experience of these interconnections.
What I found remarkable was how hard this committee came down on the core discipline itself, calling mathematicians generally “incognizant” (fighting word!) of the expanding role that the mathematical sciences now play in other realms of theory and practice. “It is easy,” the authors write, “to point to work in theoretical physics or theoretical computer science that is indistinguishable from research done by mathematicians, and similar overlap occurs with theoretical ecology, mathematical biology, bioinformatics, and an increasing number of fields.” By implication, the authors are calling their colleagues insufficiently appreciative of these connections. And in practical fields, it seems that everyone — biotechnologists, communication-system engineers, and financial-market “quants,” to take just a few examples — has proved more aware of these interdependencies than mathematicians themselves.
The National Science Foundation has issued its latest report on graduate-student enrollment in science & engineering fields, taking a decade of data up through 2010. There are now about 560,000 graduate students enrolled in S&E fields at any one time, nationwide. Among these are the people who do most of the actual lab work on federally and industrially sponsored research conducted at our nation’s universities and colleges. They are the elite of the STEM workforce: those who aren’t bound for academic and educational careers may start companies or staff big corporate R&D centers.
As usual, the NSF statisticians have done an excellent job calling out the major trends. Over the decade, one sees faster overall enrollment growth in engineering fields than in science; extremely rapid growth in biomedical engineering; and above-average growth for both women and almost all non-white minorities. Though we’re cautioned not to make too much of the year-over-years, in the 2009/2010 comparison I think it’s possible to to see the effects of priorities in the federal research budget favoring physical sciences, earth sciences, and the range of engineering disciplines pertinent to the renewable-energy and advanced-manufacturing sectors. All that’s good news.
One other observation the report makes is that graduate enrollment grew at the same rate for U.S. citizens and permanent residents as for temporary visa holders. This is bad news: after a decade of growth in graduate enrollments, some 30% of all graduate students are still here on visas that virtually guarantee their return home when they graduate. Either that, or they can place themselves at the tender mercies of an employer willing to offer a “sponsored” visa like the H-1B, a boon that can be withheld at will and thus a virtual guarantee of wage suppression.
Our disgraceful failure to offer full-fledged permanent residency to foreign students who have earned graduate degrees here not only insults the foreign born and strengthens our potential economic rivals, but it really presents American-born students with a very unhelpful object lesson: that their reward for graduate study in the STEM disciplines is to see many of the available jobs filled at preference by the exploited, often as a way-station to their complete offshoring. If we want students to study the STEM disciplines through graduate school and put those skills to work here rather than in some other nation, let’s reward all who do so with the loyalty of a grateful society.
