The problem with your logic is that you are presuming that those who are making the decision that Disney is even more valuable than it was ten years ago (by paying the higher prices this year, in greater numbers than those who paid lower prices ten years ago) are not "normal" (and that you, who feel differently, presumably are "normal"?)
"Normal" is subjective, so let's not use that as our standard, shall we?
There are two types of Disney visitor: the hardcore Disney fans who are almost obsessive when it comes to the "Disney Difference" (and who I would think would be well over 90% of the posters on this and other Disney forums) and the passive visitors who ostensibly see Disney as just another vacation destination and don't see it as being any different than any other amusement park (Carowinds, Kennywood, Silver Dollar City, any of the Six Flags parks, etc. )
The passive visitors don't really care about long term trends. They find out the cost of a vacation, budget for that vacation, and then take the vacation and return home. As soon as they get home, they typically don't think about Disney.
They don't care if an AP price has jumped $150 on a whim, and why would they? They weren't AP holders in the first place.
They don't care that the Everest Yeti hasn't moved in 11 years, and why would they? They still enjoyed the big drop and the backwards section of track.
They don't care that instead of being updated and refreshed, classic attractions are gutted to make way for the new popular thing, and why would they? They loved Guardians of the Galaxy (formerly Universe of Energy/Ellen's Energy Adventure) and it's only natural that Disney World have a Mickey Mouse ride (formerly the Great Movie Ride).
But to the hardcore Disney fans, it all matters. We care that Star Wars was turned into such a sacred cow that it's been shoved into every bit of free space at DHS, sometimes to the detriment of other attractions (ideally, Runaway Railway should have been put in the old animation building, but Star Wars was too much of a cash cow to close the Launch Bay).
We care that TDO, in the name of appealing to the masses, royally sold out Epcot Center's mission statement for popular trends (with the current debate on climate change and advancements in alternative energy sources, Universe of Energy was set for a 21st century revival....but why challenge the audience to consider real world issues and run the risk of making them feel bad, when one can just make them feel good by selling them a plastic dancing Groot and a Rocket Raccoon plushie?)
In the end, it's the hardcore fans that demand Disney hold true to its roots and the vaunted "Disney Difference", but that's not the audience that the Disney Company wants. They're focusing on short-term gains rather than long-term strategy; they're not really looking past those quarterly reports.
And don't ding me on the "Overprivileged Brazilians" quote. Because they are in fact a. From Brazil (a fact that they advertise through their matching clothing featuring colors of Brazil's flag) and b. they are very much overprivileged, thinking they can do whatever the hell they want even when cast members tell them otherwise, as evidenced last week when a swarm of them decided to stand up and start leaving the Living with the Land boats before the final stop, and refused to sit down even when being confronted directly by the cast members at the load station.
