>Lift ticket prices have become crazy expensive,
Unfortunately it's what the market will bear. Of course college kids can't out-compete the hordes of DINKs from the Boston area who decide last minute that this will be a good skiing weekend.
As other commenters have mentioned there are still reasonable prices to be had but you have to go find them. The days of just showing up on a whim and getting a fair price are over (this applies to a lot of things, not just skiing).
>the messaging here is that you have to be wealthy to be able to ski.
It's recreational activity you have to travel to and requires a lot of gear and a somewhat prepared area to do it. That sets a pretty high wealth floor no matter what.
You might be right that prices not related to climate change will kill the industry but if that doesn't happen climate change will increase prices (a mountain that's open for fewer months has to charge more to cover fixed costs) until the same effect is achieved.
