I would say another reason the sandwiches cost so much is because so many remain unsold. You have to start with the assumption that things like this are only intended for the very well-heeled to begin with, particularly in this price range where the difference between about $2 and $20 is not actually significant to the buyer. It is well-known that most travelers are not in this catagory, and plenty of millionaires will not ever spend close to $20 at the high end for something recognized as worth $2 at the low end. Even if they could do it without any financial pain. Sometimes that's how they got to be millionaires anyway. Anyway, you've got to have more than enough sandwiches for every one of the real high-rollers who might be passing through that day, you would never want to have less than enough. Plus every now and then someone else will get hungry enough to bite. There's no intention for there to be alternative choices which are more economical. So a lot of the sandwiches are going to go to waste. So they need to be able to afford to make enough to waste most of them. Which could only result in spiraling costs. Overpriced lower-quality outcomes follow greed in a self-fulfilling way when you do the math, but when all benefit is directed only to the greedy party, it does no-one any good since they are not capable of being fulfilled. Apply this to so many other parts of the economy, and look what we have. More greed and more waste to go with it, and ordinary workers can't afford what they once could.
