Another reason why spending on higher education may correlate with negative economic growth is that once students get into an academic environment, they are saturated with leftist politics and want to become lawyers or environmental activists who sue companies for creating products and try to prevent anybody from doing anything (“The Phantom Gains of College Aid,” Steve Malanga, PostOpinion, Dec. 11).

If colleges encourage more students to study engineering and science, something useful might come out of it.
