I think a related problem is that college professors are usually soft. I have been in a number of classes where a group of students take control and demand a curve, or an extension of a project, and in their defense, why not? Many if not most professors will cave. The best classes were usually taught by strict professors with the confidence to stick up for their original lesson plan.
I think a related problem is that he is interacting with "PR majors".
Communications, sports medicine, all these majors attract a disproportionate amount of slackers BECAUSE they are easy. The only reason the hard sciences are not AS BAD is because the subject matter makes it much harder to dumb down.
