So why is there demand for education if it’s so unnecessary? Because make no mistake: employers do want smart employees. You don’t want to hire someone to whom you have to explain something three times before he or she gets it. Or worse, you don’t want to hire someone who will never be able to grasp that thing, due to inferior reasoning ability. As a result, a college degree has become a proxy for determining whether a job applicant has a minimum level of intelligence necessary to perform a job. But with many private college educations exceeding $120,000 these days, that’s a pretty expensive means for identifying adequate intelligence.

Unfortunately, this may describe all a college degree has become. There was a time when a high school degree served this purpose. But when high school standards declined and college became more popular, some applicants stood out above others as being more educated and potentially smarter than those with only a high school diploma. If the trend keeps up, however, a time will come when a college degree isn’t enough either: masters degrees will be commonly sought, as the value of college degrees fall to be worth as little high school degrees are today, since so many applicants will have them. If this trend keeps up forever, perhaps we’ll one day have locksmiths with PhD’s.
