As a student who used to get good grades with low attendance, I would have found such class refunds very annoying and patronizing. It also gives students who are well-off a lot more flexibility in how they structure their time than those for whom the money matters. Putting a disincentive on resits on the other hand seems reasonable because those come at a cost. I'm not sure that that should go so far as to put a higher reward on higher grades though - trading off high grades for (e.g.) extracurriculars seems entirely reasonable to me and not like something that should be discouraged, and in general a focus on grades rather than learning seems somewhat unhealthy.
