One American research university offers its PhD students a salary of $1000 per semester for the “opportunity” to design and teach a course for undergraduates, who are each paying about $50,000 in tuition. The university calls this position “Senior Teaching Assistant” because paying an instructor so far below minimum wage is probably illegal. In addition to teaching, academics conduct research and publish, but they are not paid for this work either. Instead, all proceeds go to for-profit academic publishers, who block academic articles from the public through exorbitant download and subscription fees, making millions for themselves in the process. If authors want to make their research public, they have to pay the publisher an average of $3000 per article. Without an institutional affiliation, an academic cannot access scholarly research without paying, even for articles written by the scholar itself.
