HIGHER EDUCATION BUBBLE UPDATE: What We’re Buying With $1 Trillion+ in Student Loans:

You know what they say about doing the same thing over and over again and expecting a different result. This is certifiable. College is too expensive, so have the government make it easier to finance — then keep shifting more and more of the cost burden to the government, without doing anything about the underlying cost inflation that is making it necessary for government to get into the finance business.

Obviously, this can’t go on indefinitely. The income-based-repayment programs are relatively new, so the government hasn’t yet been handed the bill for the loan forgiveness that will be necessary as we give people payment rates that are often less than the interest on the loan. But when the government gets that bill, people are going to notice that this is a costly business.

Over decades, the government has restructured the educational system to make it look more like the health-care system, with the costs paid by third parties while the service is consumed by individuals who have no incentive to think about price. The effects are predictable for both. . . .

Does college actually make people much more economically productive? Yes, yes, I know: People who go to college earn substantially more than people who don’t, and that earnings premium has been increasing in recent decades. But what, exactly, do they learn in college that makes them so much more productive? In certain technical professions, the answer is obvious; engineers and nurses do need to master the rudiments of their trade before they are unleashed on an unsuspecting public.

But that doesn’t describe the whole higher educational system. It doesn’t even seem to describe the majority of college degrees. Administrators defending the value of degrees in “business” or liberal arts rely on nebulous claims that they are teaching students “how to think.” However, they provide little objective evidence that these programs impart thinking skills worth tens of thousands of dollars.

There’s at least some evidence that a lot of the benefit of a college degree comes not from what you learn in college, but from signaling to employers that you are the kind of conscientious, hardworking student who can get into college and stick with it long enough to get a degree. In other words, much of what we do in school is not learn anything in particular, but obtain a credential that certifies us as good potential employees.

Do tell. If you understand the federal student aid system as a means for transferring money from taxpayers to an industry that’s basically a wholly-owned subsidiary of the Democratic Party, it makes more sense.
