Do you have any evidence specifically about lecturers being bribed? Because there could be a whole other range of other explanations for why this practice continues.
working for two uk universities. and this not the only stuff these corrupt people got up to - one had the cheek to photocopy his own (crap) book using free to him university copiers, and then make his students pay for the copies. nothing was done about it, of course.
That's of course deplorable. But it just feels to me that if it happens so regularly, there must be some systemic causes and not just instances of invidual educators being bribed
what other reason can there be for very, very bad authors have new editions of books come out every year and get enforced on students by tenured clowns?
