I agree that Disney food prices are hugely inflated, but it's hard for me to get too mad about it when every local festival and amusement park in my own locale does the same thing, and when I have a meaningful choice to do something different. Disney still allows us to bring in our own food, and (subject to capacity restrictions), I'm free to come and go from the parks to dine at less expensive offsite locations if I choose. I'm fully aware that if I pay $20 for a Disney hamburger, I'm not paying for a great-quality hamburger (because it probably won't be): I'm really paying for the convenience of not having to pack it, or travel to it, myself.
As much as Disney wants its guests to think that onsite dining is a "must-do," especially for non-locals staying for long periods, it's not, and never has been. I spent my childhood Disney visits (all done on a shoestring budget, staying at the campground in our second-hand popup) eating bologna sandwiches, apples, and potato chips out of my mother's giant magical Mom purse, much as
@Lilofan describes above, and the closest we came to a character meal was dinner by Chef Boyardee. There's no shame in that kind of approach, and it's become even easier to do (and to do healthfully) in these days of ubiquitous hotel mini-fridges and grocery delivery. It's a dining model my own family is gradually moving back to, since our response when Disney raises prices isn't to pay more -- we simply
buy less.
