The only expensive thing left in higher education was the labor, the price of hiring a smart, knowledgeable person to help students when only a person would do. And the unique Smarthinking call- center model made that much cheaper, too. By putting these things together, Smith could offer introductory college courses à la carte, at a price that seemed to be missing a digit or two, or three: $99 per month, by subscription. Economics tells us that prices fall to marginal cost in the long run. Burck Smith simply decided to get there first.

Like Craigslist, StraighterLine threatens the most profitable piece of a conglomerate business: freshman lectures, higher education’s equivalent of the classified section. If enough students defect to companies like StraighterLine, the higher education industry faces the unbundling of the business model on which the current system is built. The consequences will be profound. Ivy League and other elite institutions will be relatively unaffected, because they’re selling a product that’s always scarce and never cheap: prestige. Small liberal arts colleges will also endure, because the traditional model—teachers and students learning together in a four-year idyll—is still the best, and some people will always be willing and able to pay for it.

There’s a psychological barrier as well. Most people are so invested in the idea of education-by-institution that it’s hard to imagine another way. There’s also a sense that for-profit schools are a little sleazy (and some of them are). Because Web-based higher education is still relatively new, and the market lacks information that allows students to compare introductory courses at one institution to another, consumers tend to see all online courses in the same bad light. “The public isn’t good at discriminating,” says Larry Gould. “They read ‘online course’ and they think ‘low quality,’ even when it’s not true.”
