I don’t agree with the conclusion. Mcdonalds has gotten more expensive than many high end burgers, and mcdonalds is not a high end burger.
That’s the main reason I never get food there. I realized a few years ago that I can get better food for about the same price by going to Culver’s, or if I want I can even go to a sit down restaurant for not much more. I don’t even know what their prices are like now because it’s been a few years since I last stepped foot in McDonalds
