So... former tenured professor here. I've seen both sides of the coin. I've had grad students who I felt like pulling my hair out about because they expected you to guide them through every single little thing. They were very good at following instructions to a T, but they had to have every single instruction, and if you didn't provide it, they blamed you for not providing enough guidance.
On the other side of things, I've seen extremely abusive colleagues, with recurring problems with grad students (and faculty). All sorts of abuse, from just outright aggression, including physical aggression, to coercion into academic fraud, you name it. In a couple of cases things have gotten attention but most of the time nothing happens, or the student just eventually exits the program without a degree because they've had enough.
I agree with others that the primary difference is that it seems like in the nonacademic world people have more flexibility to move elsewhere. There's a lot of fuzzy overlap between the academic and nonacademic world, but at the moment even in the best circumstances academics is rife with corruption and problems, depending on what field you're in. When you erect a pyramid scheme and come to institutionally depend on it, you're bound to run into problems.
