Serving someone well doesn’t necessarily mean making them happy. Students — people who by enrolling at an institution in a course of study admit their ignorance of that domain — do not seem to me good judges of an instructor qua instructor.
There's genuine concerns that should be reasonably heard. One example is slowness in grading homework/exams/etc. What happens is professors get backlogged, and you have multiple homework/exams and the student missed on understanding some concept they were later graded on. If the student had regular grade updates, they would know where they needed to focus more on the course material to master it. Instead, those misunderstandings snowball and you end up doing worse on a final exam since you didn't know what course concepts you correctly understood and missed.
I agree broadly with the wholistic assessment of what American colleges have become. But the review process is still germane-- classes are the core offering of college.
Classes may be what students take when they go to college, but I always thought of them more as ice-breakers for the forming of relationships with instructors and fellow students and a way to foster a community of intellectual enquiry.
I've been to both American colleges and all-inclusive resorts and, no, they don't.
And yeah, they really don't.
