Here's the thing w/re the bolded, and I fear something may be getting lost in a cross-border translation here, because Canada (by which I mean there are just different general expectations and cultural 'feelings' re who pays for what and government and personal 'responsibilities' and etc., IN A GENERAL SENSE).
People in the U.S. say basically the above, alllllll the time, w/re 'food stamps' (now SNAP benefits) and other things provided by the government to families or individuals. There is no shortage of 'we work hard and can't afford steak and I saw someone in the market buying STEAK and cake and ice cream with food stamps!! If someone is taking government benefits they shouldn't be spending $100 on an expensive dinner!! I don't spend that much and...' basically your post.
Which, everyone is saying, first, no one knows anyone's circumstances. Someone on benefits may be getting them for a whole slew of reasons, including having taken in foster kids (also in many states child support is loaded onto the same card if collected through the state). Even if it is straight up benefits to the poor though, someone may have scrimped for two weeks, making lentil soups, their own bread, etc., to have enough left over for one special expensive meal for someone's birthday or something. That's their decision, as it's their money.
There's an episode of a show called 30 Days, which was a really good show by Morgan Spurlock (who now has some issues, but the show is good -- he or someone else, mostly someone else, spent 30 days living in a different life, basically. Like he sent a 21-year-old evangelical Christian to spend 30 days living with a gay man in the Castro in SF (it wasn't an MTV shock-value type show, they were both thoughtful people open to listening -- the Christian talked to local pastors AND went to a gay bar, they had serious chats, etc.)), in which Spurlock and his then-gf lived for 30 days in a poor area, taking nothing with them, on minimum-wage jobs. At one point, when his niece and nephew visit, Spurlock and his gf have a big fight because he wants to take the kids to the movies and buys them doughnuts and she's like 'fuck you, I'm walking to my shit job to save the $2 bus fare,' and you're all, 'hey, let's spend $4 on Twizzlers and crap?' (I'm way paraphrasing, heh). He feels they deserve a break/treat, it becomes a whole microcosmic thing.
Also, you can do Disney on WAY less than that if you plan really well. Disney tickets can be had for less if you buy them certain places, you can get extra discounts if you buy everything with Disney gift cards, which you can save an extra 10% on if you buy them correctly; buy them on an airline cc and put the miles toward airfare; you can bring food into the parks and eat mostly cheap crap like granola bars and pbj you make in your offsite hotel room, etc. There are ways to do Disney cheaply if you put in a distinct amount of effort. Some people plan for a year or two to make a Disney vacation happen for their kids.
You can absolutely easily spent $10k flying, staying onsite, eating in the parks, etc., buying souvenirs. You can also spend like 1/4 of that buying souvenirs in advance at Walmart and doling them out during the trip and planning well in advance. Same as anything -- you don't know what other people are doing.
A friend of mine owns a $3500 article of clothing. I was there when she bought it. It's real. It's from Bloomingdales designer floor thing -- that she found at one of the discount houses marked down like 5x, with the original tags on it, on a clearance rack, and she had a coupon, so it was like $100 or so (she's quite tall; we suspect shorter people figured altering it would be a pita or something). Someone who knows what they're looking at who saw her in it might think she's rich or spends a fuckton on clothes. Neither is true, but ....
