I agree that Snowtime has some excellent programs and they also do a good job with groups, which is very often the way kids are exposed to skiing/boarding. What make TL and 7S really noteworthy, though, is that they strive to make a full lodging/food/lifts/lessons/equipment package available to these groups. In putting together an "introductory" group trip, lodging can be, by far, the hardest issue to deal with. Granted, for the closer in places, you can just not stay over, but for TL, etc... that is not very practical. Plus, a great deal of the experience for kids is staying in the snow in the mountains. Interestingly, one good answer is State Park cabins. PA, WV and MD all have excellent winter cabin rentals near most of the ski areas (including Roundtop). The hard part is getting into one early enough. It seems like the competition for these low cost alternatives just keeps getting more intense every year.
As to the cost of skiing overall, I don't think that having high end/high service offerings is bad as long as some lower cost options remain. But if only the well off can afford to ski, then only the well off will ski. And many, many smaller areas (read Mid Atlantic) will go under.
Of course, there is always the really high end option - turn your ski area into a "country club" where ONLY members and guests can enter. It's already proving to be a successful model at the Yellowstone club, and, if I owned TL, it certainly could be a viable option. Sell a membership for, oh 80 to 100K, charge an annual fee (10K maybe), and simply close the doors to everyone else.
It could happen.....
