So glad I left the publishing industry. I went in with a lot of respect many years ago, but it was so gross. All about how much money could be milked from students. Accuracy of information was in second or third place of importance
100%. They ripping off students selling books that are often complete garbage. In my experience “calculus” is a great example. The material is completely ossified in like the 1700s. The books are worthless tomes of useless calculations (especially in the age of computers). The whole system is about taking money, filtering people by useless exercises, and keeping people brainwashed and controllable. There’s almost zero mathematical education. If they’re lucky, the fundamental theorem of calculus will be mentioned for a few minutes. That’s the peak of most people’s education in math. It’s pathetic.
