Bryan Caplan blows the whistle.
I have been in school for more than 40 years. First preschool, kindergarten, elementary school, junior high, and high school. Then a bachelor’s degree at UC Berkeley, followed by a doctoral program at Princeton. The next step was what you could call my first “real” job—as an economics professor at George Mason University.
Thanks to tenure, I have a dream job for life. Personally, I have no reason to lash out at our system of higher education. Yet a lifetime of experience, plus a quarter century of reading and reflection, has convinced me that it is a big waste of time and money. When politicians vow to send more Americans to college, I can’t help gasping, “Why? You want us to waste even more?”

The labor market doesn’t pay you for the useless subjects you master; it pays you for the preexisting traits you signal by mastering them. This is not a fringe idea. Michael Spence, Kenneth Arrow, and Joseph Stiglitz—all Nobel laureates in economics—made seminal contributions to the theory of educational signaling. Every college student who does the least work required to get good grades silently endorses the theory. But signaling plays almost no role in public discourse or policy making. As a society, we continue to push ever larger numbers of students into ever higher levels of education. The main effect is not better jobs or greater skill levels, but a credentialist arms race.
