The cost will continue to be passed on to you until there is a robust discussion about the financing model and the working conditions in academia. If any change is going to happen it's going to come through student effort; despite their protestations the position of the unions and the professors is to preserve the status quo. Back then we'd call this "revolutionary consciousness".

The goals of the students will also need to be taken into account. A colleague gave up giving detailed comments on the lab protocols he graded, the only thing the students were interested in was the grade. My experience matches. It's understandable, at our institution students mostly plump for medical school or associated profession, and it's the grade that counts, not the subject knowledge. The GPA really haunts you.
