I can give you concrete evidence from my personal experience that, in general, upper management does not care about the guests. I'm not talking about an area manager in operations, I'm referring to the ones that make decisions as to what kind of quality will be produced for the parks.
While working at WDI, and also working for them on a contractual basis, there have been more than a few times that I have heard upper management say things like, "who cares if that show element 'pops' or 'flops'...they'll never know the difference"...or, "just put a coat of paint on it...we don't need to make it look great just acceptable." How about, "it doesn't matter what we put there the marks will continue to pay admission and buy merchandise." I'm not exaggerating when I tell you that there are more examples of these kind of remarks than I could possibly remember and they are not all from the same executive.
You can continue to believe what you want but I'm telling you that, at least as far as WDW is concerned, you are getting a far lesser product than what you should be getting in part due to Disney's lack of concern, and in some cases, even contempt for their customers. No it's not an official Disney policy but it's the reality of WDW today.
This is disheartening, but I have a few thoughts.
I work in a building with only 60 adults, and you would hear similar attitudes from a few of our people as well. Most of us, and most people I've worked with at different jobs, actually do care about people, product and have some pride. So am I surprised you heard that comment? Nope, not at all. I am not naive enough to believe that with 150,000 employees that some won't have these attitude. It's also been my experience that people who feel this way about their work, tend to be the loudmouths in the company.
I don't believe the sky is falling or this is the prevailing sentiment. This attitude very rarely, if ever, represents the feelings of the majority.
Further, I feel that had you been working for or around WDI 20 years ago, you could have heard this. There have
always been people who have no pride, passion or simply don't care at all places of employ. I doubt even all the Disney employees in the early days cared. After the strike of 1941, Walt was content that several hundred of those animators who didn't care were gone. Yep, always been people who try to dish out sub standard crap.
How does this affect me? well, some will argue that all the people with this poor attitude ensure that all we get at WDW is subpar; at least until there are changes in upper management. I disagree. On this point, there will be a very wide variety of opinions, but that's irrelevant. All that matters is, as spacemt354 noted, is the microexperience. My vacations at WDW involve experiencing the world from my point of view. I interact with CMs, eat at restaurants, partake in recreation, stay at resorts and visit parks. If what I experience is subpar imho, I'll talk to guest relations, write a letter, or simply vacation elsewhere. I've never had that experience yet. During my visit 3 months ago, doing parks daily and spending 9 nights on property, I saw about 5 minor things wrong and a million (slight hyperbole) that I was happy with. The executives you've overheard did not cause anything that I noticed. Perhaps they have little influence.
