Yes. I could certainly bring the costs down, but at the expense of the experience of the students.

I don't believe that is an ethical choice, even if the students are already extremely privileged.

I do struggle with this every few months though, it is a difficult concept to grapple with, but I always side with trying to provide the best educational experience that I can.

And FWIW, among the other instructors, my costs aren't even particularly high.
