A Disney holiday as a pre-teen or early childhood milestone was only true amongst a subset of middle class Americans during the 1960s-2000s.
Heck, the first time I visited Disney was during my high school graduation with the subsidized HS Disneyland grad trip which Disney created in order to create a monetizable nostalgic customer base that became 'Disney Adults'.
Most people globally never experienced that, and only really care about Disney from a teen or adult oriented lens.
A high earning single person household flying in from Beijing or a DINK household in NYC spending $1-2K at a Disney resort is more valuable and provides better margins than a household of 4 spending $600 on Disney (and most likely won't stay at the resort).
It's the same strategy the foreign Disney Experience properties (Paris, Hong Kong, Shanghai) and the Walt Disney cruises use as well.
You aren't a bad parent if you didn't take your family to Disneyworld - in fact they don't really want your money anymore.
