Over the past 25 years the total number of students in college has increased by about 50 percent. But the number of students graduating with degrees in the vital fields of science, technology, engineering and math (the so-called STEM fields) has been flat.
Further exacerbating this problem is that, of the few graduates in those fields, many are foreign-born and often return to their native countries upon graduation. Altogether then, the United States is producing a proportion of college graduates in STEM fields far smaller than it did in years past, says Alex Tabarrok, an associate professor of economics at George Mason University.
