Imagine that America had no system of post-secondary education, and you were a member of a task force assigned to create one from scratch. One of your colleagues submits this proposal:

First, we will set up a single goal to represent educational success, which will take four years to achieve no matter what is being taught. We will attach an economic reward to it that seldom has anything to do with what has been learned. We will urge large numbers of people who do not possess adequate ability to try to achieve the goal, wait until they have spent a lot of time and money, and then deny it to them. We will stigmatize everyone who doesn't meet the goal. We will call the goal a "BA."

You would conclude that your colleague was cruel, not to say insane. But that's the system we have in place.

Finding a better way should be easy. The BA acquired its current inflated status by accident. Advanced skills for people with brains really did get more valuable over the course of the 20th century, but the acquisition of those skills got conflated with the existing system of colleges, which had evolved the BA for completely different purposes.

Outside a handful of majors -- engineering and some of the sciences -- a bachelor's degree tells an employer nothing except that the applicant has a certain amount of intellectual ability and perseverance. Even a degree in a vocational major like business administration can mean anything from a solid base of knowledge to four years of barely remembered gut courses.
