Class is often overlooked as a driver of observed career and wealth disparities. This paper is a pretty incredible study into the role of class in the career progression of academia. Class has a substantial impact at nearly every stage of the academic pipeline. Important work. On a personal note, this tracks with my own experience as a first-gen student. In grad school, I was shocked at the number of peers who had academic parents. They arrived on the first day knowing about the journal publishing system, the importance of conferences for networking, etc.
