I honestly think that a lot (maybe not most, but a lot) of Vail and Aspen's visiting skiers are happier when prices go up. I know it sounds crazy, but some of these people have a LOT of money. I've seen how they throw it around. A lot of them might ride the lifts up at noon, take one run, head into the restaurant to drink wine for the next two hours, take another run or two, and head home. I've also seen how they talk to their friends, and for some of them, a ski vacation is really a status symbol.
I dunno, it sounds crazy, but after working various customer service jobs in Aspen throughout high school and off and on during college for the past few years, its the sense that I've gotten.
