Most universities in America are currently structured so that the students who want to learn can learn, and the students who don't want to learn can coast along between parties for four years. Giving low grades, failing students, assigning a lot of mandatory homework, making the minimum that's required remotely challenging, giving students more than a slap on the wrist for any infraction -- all of that drives away the coasting students, and that's bad for enrollment. If this professor continues to fuss over this, all he's going to do is botch his chance at tenure.
