Eduardo Porter, a business columnist for the New York Times, writes enthusiastically about a new and inexpensive way to “skip college.”

He writes:

“This week, AT&T and Udacity, the online education company founded by the Stanford professor and former Google engineering whiz Sebastian Thrun, announced something meant to be very small: the “NanoDegree.”

“At first blush, it doesn’t appear like much. For $200 a month, it is intended to teach anyone with a mastery of high school math the kind of basic programming skills needed to qualify for an entry-level position at AT&T as a data analyst, iOS applications designer or the like.

“Yet this most basic of efforts may offer more than simply adding an online twist to vocational training. It may finally offer a reasonable shot at harnessing the web to provide effective schooling to the many young Americans for whom college has become a distant, unaffordable dream.”

“Intriguingly, it suggests that the best route to democratizing higher education may require taking it out of college.

“We are trying to widen the pipeline,” said Charlene Lake, an AT&T spokeswoman. “This is designed by business for the specific skills that are needed in business.”

“Mr. Thrun sounded more ambitious about the ultimate goal: “It is like a university,” he told me, “built by industry.”

Correct me if I am wrong, but this sounds very much like vocational training, not college.

Porter rightly says that college is out of reach for many young people, and he is right. One of the reasons it is out of reach is that many states are shifting the financial burden from the public to the student. That’s short-sighted. Surely higher education should be available to many more young people, and the way to make it more affordable is to reduce the cost by government subsidies.

Job training is not enough. The doors to higher education should be open to all who have the will and the ability to pursue it, without regard to their income.

Once upon a time, community colleges were free. Once upon a time, states subsidized public higher education to keep costs low.

Here is a book that argues that public higher education should be free. What a dream. Our society invests our treasure elsewhere.
