I think you all are missing my point. Yes, the middle class. But the upper middle class over the single mom working at Wall Mart. Two income families over single income families. Income statistics as a whole don't apply to this board because the most common income (modal income) in America is something like $8000 - and who here makes $8000. The average Disney guest is the wrong population for this board because the average Disney guest is either a day tripper or going for a once or twice in a lifetime trip - that isn't many people here. And because there are people pushing the average up because they make $500M, who here makes $500M? Does Disney have a problem attracting affluent customers - well, it depends on how you define affluent. The number of Deluxe hotel rooms booked says there are people who can spend $500 a night or more on a hotel room - or go over to the DVC board - there are lots of people who own over 1000 DVC points (that's about $100,000 in resale value). The number of signature restaurants booked says there are people who aren't eating at Peco's Bills. The number of $50 a person character breakfast sold says that there are people who disposable income. There may not be as many of them as Disney would like - because honestly, they'd rather have more of them. And accountants and teachers and software developers are the working class. But the lowest household income quartile tops out at $24,638 (2017) - 20% of Americans make less than that (and that's pretty close to the poverty line for a family of four). We can cut those people out of visiting Disney - and being regulars on this board - almost completely. Tickets alone aren't affordable except perhaps as a splurge, much less hotel rooms, travel - you'll certainly get some regional day guests - and of course theme park employees and college students in that range, and those with wealth whose income is low, but are living off their wealth. On the other hand, the top quartile starts at $104,000 - that isn't really affluent - no one has gold toilets on $104,000 a year, but that does permit a family to make regular Disney trips if that's their thing - unless they live in a really high COL area.
There is a huge middle ground between affluent and poor. Affluent people don't go to Disney as much as Disney would like. Poor people can't go at all.
Your assumption is that people who stay at Deluxe properties and eat at premium dining experiences are well off; I've been arguing the opposite. Trade publications estimate that the average nightly rate at many Deluxe WDW resorts is similar to or higher than at comparable properties (all brands) in Hawaii -- but the people staying in Hawaii have twice the income. Reality is, the core WDW guest is likely solid middle class and overindulging. Just reading this forum illustrates that -- there's oodles of posters who frequently post ridiculous dollar amounts as "necessary" to visit WDW "or it's just not magical" ... and the same posters seek advice in the Budget Board on reducing their debt or lowering expenses (hint: you don't need to spend several hundred dollars every year to take your family to the Hoop-De-Doo ... yes, your vacation will be magical without it).
My favorite poster was somebody who posted elaborate trip reports about enjoying the high life at WDW (always concierge level rooms at Deluxe properties, etc.) In 2006, he/she posted about seeking help with their bankruptcy filing... you know, because times were tough, not because their family took annual $20K trips to WDW!!! I've wrote it before and I'll write it again - people who are actually good at managing their fiances would never spend the sums of money on a WDW vacation that many posters promote as "average" or "necessary" to have a "magical" experience. People who are truly well off perceive magic to be their money making them more money (e.g. interest, dividends, gains, etc.), not some $10 corn dog or $4 soda.
