In tough economic times, it’s easy to gin up anger against elites. The bashing of bankers is already so robust that the economist William Easterly has compared it, with perhaps a touch of hyperbole, to genocidal racism. But in recent months, a more unlikely privileged group has found itself in the cross hairs: tenured ­professors.

At a time when nearly one in 10 American workers is unemployed, here’s a crew (the complaint goes) who are guaranteed jobs for life, teach only a few hours a week, routinely get entire years off, dump grading duties onto graduate students and produce “research” on subjects like “Rednecks, Queers and Country Music” or “The Whatness of Books.” Or maybe they stop doing research altogether (who’s going to stop them?), dropping their workweek to a manageable dozen hours or so, all while making $100,000 or more a year. Ready to grab that pitchfork yet?

That sketch — relayed on numerous blogs and op-ed pages — is exaggerated, but no one who has observed the academic world could call it entirely false. And it’s a vision that has caught on with an American public worried about how to foot the bill for it all. The cost of a college education has risen, in real dollars, by 250 to 300 percent over the past three decades, far above the rate of inflation. Elite private colleges can cost more than $200,000 over four years. Total student-loan debt, at nearly $830 billion, recently surpassed total national credit card debt. Meanwhile, university presidents, who can make upward of $1 million annually, gravely intone that the $50,000 price tag doesn’t even cover the full cost of a year’s education. (Consider the balance a gift!) Then your daughter reports that her history prof is a part-time adjunct, who might be making $1,500 for a semester’s work. There’s something wrong with this picture.

The debate over American higher education has been reignited recently, thanks to two feisty new books. ­Higher Education? How Colleges Are Wasting Our Money and Failing Our Kids — And What We Can Do About It (Times Books, $26), by Andrew Hacker, a professor emeritus of political science at Queens College, and Claudia C. Dreifus, a journalist (and contributor to the science section of The New York Times), is if anything even harsher and broader than the cartoonish sketch above. It is full of sarcastic asides like “Say goodbye to Mr. Chips with his tattered tweed jacket; today’s senior professors can afford Marc Jacobs.” But its arguments have been praised in The Wall Street Journal and given a respectful airing on The Atlantic’s Web site. They are also echoed in Mark C. Taylor’s Crisis on Campus: A Bold Plan for Reforming Our Colleges and Universities (Knopf, $24), which is more measured in tone but no less devastating in its assessment of our unsustainable “education bubble.”
