I like McDonald's on occassion. The problem with most people who get obese on it is that they don't treat it as a luxury, they treat it as an everyday thing.

The Dollar Menu makes things bad because instead of just trying to get cheap food, people think "Well, instead of getting a Big Mac combo for $5, I can get five $1 Double Cheeseburgers! Score!" It's pretty good or bad psychology, depending on how you look at it.
