There is no such thing as practical knowledge, and so there is no such thing as a practical major. This country graduates 350,000 business majors a year. The metrics for those degrees are generally awful. But nobody ever includes them in their arguments about impractical majors, despite those bad numbers. And if you’re some 19 year old, out to choose a career path, business sure sounds practical. So they graduate with those degrees and flood the market with identical resumes and nobody will hire them. Meanwhile, they lost the opportunity to explore fields that they might have enjoyed, that might have deepened the information acquisition and evaluation skills that would allow them to adapt to a whole host of jobs, and that might have provided a civic and moral education. All to satisfy a vision of practicality that has no connection to replicable, reliable economic advantage.
What’s most depressing of all is that these changes of fortune for particular fields is always seen as worthy of mockery and not sympathy. I searched around for that New Republic article on social media and found plenty of people laughing at these kids and calling them chumps for following an educational fad. You just can’t win: if you pursue a field you actually like, they mock you for your impracticality. If you pursue a field out of a desire to chase the money, and you get unlucky, they mock you for choosing poorly. Whatever it takes to convince you that your unemployment is your own fault and not the fault of an economic system that serves only the 1%.
