University of Tennessee law professor Glenn Reynolds, better known as Instapundit, is the author of The New School: How the Information Age Will Save American Education from Itself.

His latest column asserts that because American colleges today are fraught with petty politics and bad economics, higher education is rapidly coming a punchline to a very bad joke.

…The decline in enrollment seems to be slowing, but the long-term problem remains: With costs growing, and post-graduation incomes stagnant or worse, students (and parents) are growing more reluctant to take on the extensive debt that is required to attend many private, and some public, institutions.

That is only made worse by the decline in higher education’s image, damage that is mostly self-inflicted. As Twitter wag IowaHawk japes: “If I understand college administrators correctly, colleges are hotbeds of racism and rape that everyone should be able to attend.”

That sums it up pretty well. Though the claim that one in five women on campus is sexually assaulted is pretty clearly bogus — as Bloomberg’s Megan McArdle notes, it includes things like sexual touching over clothes, which hardly constitute rape — it’s widely repeated, and that surely makes young women a bit less enthusiastic about attending. Then all the responses — involving, basically, kangaroo courts that strip male students charged with sexual assault of all due process protection — don’t make campuses more appealing to male students, who are already an under-represented minority on most campuses.

Then there’s the race hysteria. Just last week, students at the University of St. Thomas in Minnesota canceled a “Hump Day” celebration featuring a camel because someone thought the camel signified racism against Muslims. (Yes, Muslims aren’t a race, but that doesn’t matter, apparently.) We make fun of Victorians for substituting the term “limbs” for the too-racy word “legs,” and for supposedly covering table legs with cloth, but our own era is prone to similar over-delicacy, and campuses — supposedly centers of critical thought — seem to be the worst offenders.

Dartmouth cancelled a charitable fund-raising “fiesta” because one student complained that the word “fiesta” was racist. And going beyond race, commencement speakers, ranging from Condi Rice at Rutgers to Christine LaGarde at Smith, have been turned away by rabid student protests, mocked here by Yale Law’s Stephen Carter.

From the economics to the politics, colleges and universities are looking less like serious places to improve one’s mind and one’s prospects, and more like expensive islands of frivolity and, sometimes, viciousness. And that is likely to have consequences.

Industries with bad reputations face declining markets and more regulation. At this rate, that’s where higher education is headed. It’s not clear at all that its leaders appreciate the depth of the problem.
