I didn't insist that students don't work hard, @OchonAgusOchonOh 😀. Where did you get that from? I asked how parents knew, and what 'working hard' meant to them, as there is no objective definition of which I'm aware, and anyway most 18-21 year olds don't have parents standing over them as they work.
I realise that medical students don't learn by osmosis, and I didn't say that, either. Nor did I say that students are lazy and do very little work - that is in your head, not in my post - which, ironically, you quoted. With respect, I'd hope that if you have a degree you were marked down on accurate understanding of text, and for misrepresenting your source material.
My point is that however hard someone works at learning, a degree measures results, which, IMO, is as it should be. Even then, there are students, often encouraged by helicopter parents, who see paying towards fees as entitling them to high marks, and if the course they've chosen has assessment styles that they don't like (eg presentations or exams) they push for exemptions, even if the career the course will qualify them for needs skills in those areas.
That sort of thing lowers standards, but is difficult for staff to resist in the current climate.
