Food is one of the joys in life that people can enjoy no matter where they are on the socioeconomic spectrum.

In the modern age, if you're poor, or just time poor, you can enjoy a tasty meal thanks to cheap food coming out of the modern food industry.

Why would you pay more for a less enjoyable experience when tasty food might be one of the only joys in an otherwise mundane or hard-up existence?

This is exactly why McDonalds is popular. It tastes relatively good, it's comforting, and it's cheap.
