An op-ed praising 1950s values provokes another campus meltdown— from the deans on down.

To the list of forbidden ideas on American college campuses, add “bourgeois norms”—hard work, self-discipline, marriage and respect for authority. Last month, two law professors published an op-ed in the Philadelphia Inquirer calling for a revival of the “cultural script” that prevailed in the 1950s and still does among affluent Americans: “Get married before you have children and strive to stay married for their sake. Get the education you need for gainful employment, work hard, and avoid idleness. ... Eschew substance abuse and crime.” The weakening of these traditional norms has contributed to today’s low rates of workforce participation, lagging educational levels and widespread opioid abuse, the professors argued. The op-ed triggered an immediate uproar at the University of Pennsylvania, where one of its authors, Amy Wax, teaches. The dean of the Penn law school, Ted Ruger, published an op-ed in the student newspaper noting the “contemporaneous occurrence” of the op-ed and a white-supremacist rally in Charlottesville, Va., and suggesting that Ms. Wax’s views were “divisive, even noxious.” Half of Ms. Wax’s law-faculty colleagues signed an open letter denouncing her piece and calling on students to report any “bias or stereotype” they encounter “at Penn Law ” (e.g., in Ms. Wax’s classroom). Student and alumni petitions poured forth accusing Ms. Wax of white supremacy, misogyny and homophobia and demanding that she be banned from teaching first-year law classes. Ms. Wax’s co-author, Larry Alexander, teaches at the University of San Diego, a Catholic institution. USD seemed to be taking the piece in stride—until last week. The dean of USD’s law school, Stephen Ferruolo, issued a schoolwide memo repudiating Mr. Alexander’s article and pledging new measures to compensate “vulnerable, marginalized” students for the “racial discrimination and cultural subordination” they experience.

Two aspects of the op-ed have generated the most outrage. Ms. Wax and Mr. Alexander observed that cultures are not all “equal in preparing people to be productive in an advanced economy.” Their critics pounced on this statement as a bigoted, hate-filled violation of the multicultural ethic. In his response, Penn’s Dean Ruger proclaimed that “as a scholar and educator I reject emphatically any claim that a single cultural tradition is better than all others.” But that wasn’t the claim the authors were making. Rather, they argued that bourgeois culture is better than underclass culture—specifically, “the single-parent, antisocial habits, prevalent among some working-class whites; the anti-‘acting white’ rap culture of inner-city blacks.” The authors’ criticism of white underclass behavior has been universally suppressed in the stampede to accuse them of “white supremacy.”

The op-ed’s other offense was extolling the 1950s for that decade’s embrace of bourgeois virtues. “Nostalgia for the 1950s breezes over the truth of inequality and exclusion,” five Penn faculty assert in yet another op-ed for the student newspaper. In fact, Mr. Alexander and Ms. Wax expressly acknowledged that era’s “racial discrimination, limited sex roles, and pockets of anti-Semitism.”

None of the professors’ high-placed critics have engaged with any of their arguments. Mr. Ferruolo’s schoolwide letter was one of the worst examples. The dean simply announced that Mr. Alexander’s “views” were not “representative of the views of our law school community” and suggested that they were insensitive to “many students” who feel “vulnerable, marginalized or fearful that they are not welcomed.” He did not raise any specific objections to Mr. Alexander’s arguments, or even reveal what the arguments were.
