Yes, these academic idiots get their cushy tenured positions and suddenly think they're God's gift. Using other appropriate textbooks don't fit their classes so they BILK you for "their" books and downloads. Nothing but a bunch of egomaniacal narcissists spouting leftist bullshit. Most of them couldn't find a job outside of academia because they have no real skills. It's been that way for far too many years and maybe Trump can finally get rid of the corruption and nonsense.
