Those cheap lesson and rental packages seem to have also gone away..
What makes you say this? Midseason, spur of the moment never-ever can still get a good deal on rental/lesson/lift ticket bundle. You can get these a few days in advance. If you walk up 'day of' wanting to do ski/lesson combo, you are either an idiot or have terrible friends. Seriously, you need to put at least a little bit of forethought into this sport and have the common sense to understand that purposely standing on a slippery, sloped surface for long periods of time is dumb and should be first experienced with some professional guidance.
My experience is based on skiing in CO/UT/NV/CA. Those that ski a few days a year and are cost conscious start planning their trips now, if not earlier, to get the maximum deals $$. The epic day pass was made for those people. I used to ski with a group of serious cheapskates and it was a game to see how little they could spend. For lunch, 3-4 of them share a bowl of chili and get a giant pile of crackers in the lodge. There was a time when you couldn't get lift tickets to Vail more than 2 weeks out (other than the epic pass).
If you are cheap and don't plan ahead, yes, you are screwed. But you were screwed before, just not as badly.
For gear - the few day a year person has a ski jacket, goggles, and pants that are 10 years old. They rent skis, boots, helmet (or don't use one). Mid layers and everything else is stuff that can be multipurpose use. All the equipment is bought from home, or if found on mega-sale at the resort. If there is a wardrobe malfunction, duct tape can be used. Last resort is buy stuff at the resort (again for cost conscious). You buy your jacket/pants in the offseason at Sun & Ski, Walmart, etc, or online for cheap. Or you borrow stuff from a friend who skis.
Now if you are a sometimes skier that doesn't plan ahead, you are going to get fleeced with walk up tickets. Some can afford it and don't care. Others that care are in for a hard lesson and will adapt behavior for next season. It's a tax on people who don't have time or care to plan.
