OK, here is the solution. Because the population of ski instructors in the US, and the organization that purports to represent it, seems powerless to protect itself against the avarice of ski area management and owners, it falls to the students to catalyze change. Under no circumstances should anyone taking lessons tip even a penny. Should an instructor remonstrate or even look out of sorts at this, explain that it is for their own good, that students are fed up subsidizing companies that charge $700 a day for a private lesson and expect the student to pay the instructor's wage on top of that. Of course, students understand that this strategy will drive instructors to penury and starvation, causing them to resign en masse and take up jobs as realtors in ski areas - thereby, and as a side benefit, reining in the outrageous commissions raked in by these land sharks.
It will be tough, and the road will be long, but finally the supply of qualified instructors will dwindle to the point that even the most naive rube of a student will rebel against being fobbed off with a kid from Argentina. Ski area management will ultimately capitulate and agree to a viable economic deal for the true pro instructors. At least a generation or two of instructors will be lost - that is the price of revolution. Perhaps Trekchick can start a roll call, "Heroes of the Revolution", that can memorialize those who fell.
And let's solve the hunger AND overpopulation problems by having the poor eat their children. There could be recipes developed and everything . . . see? More jobs!! Genius.
Well played, @HardDaysNight, well played. I always appreciate some Swiftian humor.
