I agree with most of this except the bolded part. Look, I think Disney does less of this than they did 20 years ago. I think some of the day to day magic has been used up in search of profits. But I also know people who have had things go wrong on their vacation and Disney has been absolutely magical to them during the trip and following up afterward. I also think that while it is fair to grumble about 1999 through 2012, and in fact grumble may not be strong enough because the investment during that period was non-existent, since then WDW has been trying to play catch up. New Fantasyland, Pandora, TSL, SWL are all significant investments in bettering the experience.
They do need to keep it up. They are absolutely playing catch up from the fallow decade and I agree that they haven't made up for it and even opening everything that is planned to be open by 2020 probably isn't enough. EPCOT is an absolute embarrassment as far as I am concerned. FEA is a joke in the wrong spot and Futureworld is pathetic. So they have significant work to do, but they ARE doing it at this point. And continually saying that they aren't trying or aren't doing it simply isn't true, they just have a ways to go.
As for ticket prices, WDW has increased ticket prices every year it has been open. It's not going to change. They do owe us more for the decade plus they raised tickets without adding to the parks and we will have to see how much we get for it versus the size of the ticket and hotel increases going forward. Whether it is worth it or not is very much a value judgment. I still love Disney, I love Fort Wilderness even though it is nowhere near the Fort Wilderness of the late 80s heyday, but I go less now than my parents took me then, even though we live closer. Mainly because I can't afford to go as much.
That's the side of Disney that isn't so magical, and I'm not blind to it, but I think sometimes we fall so strongly on one side of the argument or the other that the reality is actually lost in the rhetoric.
