The Atlantic's Megan McArdle says that academic tenure's heyday has passed — the practice is now too costly and "transparently self-serving," she writes. McArdle also suggests that the practice stifles diversity and innovation rather than enhancing it. "The best you can say of the system is that it preserves a sort of continuity in schools that is desirable for the purposes of cultivating alumni donations," she writes. She also discusses the process of achieving tenure in the current academic career climate. PhDs and postdocs, McArdle says "are back on the job market near entry level at an age when most of their peers have spent ten years building up marketable skills."
