Alex Tabarrok points out that the widely reported student debt problem is made much worse because students are taking courses that don’t lead to higher-paying jobs:
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 science, technology, engineering and math (the so-called STEM fields) has remained more or less constant. Moreover, many of today’s STEM graduates are foreign born and are taking their knowledge and skills back to their native countries.
Consider computer technology. In 2009 the U.S. graduated 37,994 students with bachelor’s degrees in computer and information science. This is not bad, but we graduated more students with computer science degrees 25 years ago! The story is the same in other technology fields such as chemical engineering, math and statistics. Few fields have changed as much in recent years as microbiology, but in 2009 we graduated just 2,480 students with bachelor’s degrees in microbiology — about the same number as 25 years ago. Who will solve the problem of antibiotic resistance?
If students aren’t studying science, technology, engineering and math, what are they studying?
In 2009 the U.S. graduated 89,140 students in the visual and performing arts, more than in computer science, math and chemical engineering combined and more than double the number of visual and performing arts graduates in 1985.
It’s still true that students who graduate from university will tend to have higher lifetime earnings than their peers who do not get degrees, but there’s a huge difference between the expected earnings from an engineering degree than from a “studies” degree.
