Why are ski lessons so expensive??

For reference, I used to work at a ski resort and I worked with instructors, so I had a pretty good understanding of what they made hourly. I (wrongfully) assumed that ski lessons wouldn't be much more, maybe 3 or 4 times what they make hourly, not FOURTEEN TIMES what they make hourly. JFC! I even looked at other resorts and it is still significantly more.

I guess I'm just going to have to learn how to improve my technique on my own.

Ski instructors, are y'all okay??? You're seriously getting take advantage of.
