I was saying that we should compare apples to apples. Or simply judge the prices by how much they have gone up vs. inflation and the real world.
To compare a hot dog at WDW to one at an NFL Stadium is like saying 'well, Mickey is better because he only broke my kneecaps and knocked out my front teeth while the NFL also broke both arms and punctured a lung too.'
Because one entertainment venue gouges worse, doesn't make what Mickey's minions do OK.

Although I do not have the hard facts in front of me... but based on my life experiences of going to Redskins Games (my afformentioned example of $20), Capitals Games, College Football Games, Kings Dominion, Six Flags in Maryland, Pro & College Basketball, and taking in a movie at a national chain theater...
I can make the observation that the prices that Disney charges for its concessions and quick service meals are very similar to all the above entertainment venues. Sometimes worse... sometimes better.
You could argue, and I believe you have, that Disney should not follow the crowd and keep prices for this lower, possibly kept along the lines of a shopping mall food court prices. But the problem with the notion is the food service operations are not just funding themselves and their own isolated operations within the park.
This is where the apples to apples comparison lies.
The additional money that a consessions/foodservice location takes in is also spread across the park to cover operations that don't have a revenue stream. Street sweeping doesn't have a revenue stream. Fireworks displays on regular nights, does not have a stand setup so guests can purchase a mortar that will be launched at night. I can go on but you get the point. Most every other entertainment venue that I mentioned earlier is the same. They don't/can't depend on gate ticket sales to cover all of their expenses and still be able to turn over some form of a profit.
I would like to offer up an additional theory. And maybe those of you who actually were walking and paying for your park experiences in the 70s can offer up some insight. (I was in diapers being pushed around the park in '78) As best as I can understand history, Disney had the A - E Ride tickets until Epcot opened. The older 1970s system of park admission and sale of ride tickets, possibly brought in more $$ as a % of the overall revenue stream, than a park admission does today.
If this theory is true, then this might explain why prices for food, merchandise, and other services in the parks needs to be higher. I don't have a statement of income from the park operations of the 70's vs today to compare or provide proof that my theory has merit... but its possible the change in park admission could explain the need for higher margins from food sales.
anyways... I may not have answered all of your questions in the above... but let's see.
