The biggest problem I see is that
Disneyland continues to market itself as this magical place for
everyone, but it's priced itself far out of that market (even with deals like Costco Travel and all) while continuing to advertise like crazy to that same market who can't afford it anymore. Compare that to something like the Viking Cruises that were advertised on PBS before Downton Abbey. They were extraordinarily clear that these were luxury cruises for people who have a lot of money, so ok, fair enough. It may be fun to pretend that there's "no harm" in Disney charging as much as it wants and pricing people out (and hoping that more people are priced out), but then again, it's always been easier to be on the side of "I can afford this so too bad for you." Greed and self-interest are closely related, of course.
As far as the "comparable tickets" example goes, I had to chuckle at the Breckenridge example because I just bought one-day discounted lift tickets for our family for the nearby Loveland Ski area where the one-day price was $46. I'll get the same day of skiing for half the price. Sure, Loveland isn't as ritzy as Breckenridge, but it suits our budget and we'll have just as much fun. But there's only one Disneyland and one WDW without the option of scoring cheaper tickets like I did for skiing next week.
Remember, Walt Disney himself priced things so that guests would leave with a little money still in their pockets, in part because he thought it would encourage loyalty--and probably in no small part because the man himself had literally gone hungry when he was young and knew exactly what it was like to be poor. He was worried about being greedy and was more concerned about that than profit margins.
We don't live in that world anymore, but that doesn't mean that Disney can't be greedy. I think what it does mean is that some people don't want to feel badly about their own lofty financial situation, so they shout down anyone who suggests greed plays a role.
