The rate of return lessons at most ski areas ain't high, especially for the level of lesson taught mainly by level 3. There are national stats on this, so the market assessment of instructor value isn't a small sample size issue. There's nothing unsubstantiated about the undertone you hear; the market has spoken with a deafening roar. It's economic fact. Pull out your earplugs and deal with it.
Do you have a link or something that actually documents your statistics?
