Suppose you're going to disney for a week as a family of 4.
6 days of tickets for 4 people is $2,400. Cheap jetblue tickets on sale might be $1000; honestly, they're probably more. If you're staying at a $350/night hotel room, you're already up to $5,500.
Then, figure at least $50 in food per person per day, or $100 for the adults if you get alcohol. That's another $1,200-1,800. And if you go to any of their fancier restaurants it'll be a lot more. Add in a couple hundred in souvenirs and you're there.
Of course, if you're within road trip distance and just go to the park for two days, you could do it way cheaper.
You'd have to be budget conscious, but it's doable if you're not eating anywhere sit-down, don't drink soda, and don't get snacks. But yeah, the average person is probably spending $100+.
For example, at Hollywood studios, the oats at the star wars location are $7. A chicken club and fries for lunch at ABC commissary are $18. A pizza for dinner is $12. That's $37; not sure what it would come to with tax.
They allow carry in food, so pack sandwiches and snacks and you can skip lot of the food upcharges. That's what I did for our recent big trip with family who grew up going to Disneyland regularly
Most people don't live close enough to Disney for a day trip. A significant portion of that 8k is probably the other costs of the trip like airfare and hotel rooms.
That's like a couple parents and a few kids. I don't get the appeal of spending thousands of dollars just to wait in line and be surrounded by a bunch of annoying people.
It is genuinely an experience to remember for a lifetime, because every tiny forgettable detail is meticulously designed. The staff are painstakingly always watching for anything that might ruin someone's day and anything that can make someone's day.
Basically, don't judge what other people choose to spend their money on
I can and will judge people for what they spend their money on and I expect people to do the same to me. I don't care what people do with their own money but doesn't mean they're immune to judgment.
