Agreed. If society changed, McDonald's would be forced to carry non-grease, higher-protein food items. Who knows, in 25 years McDonald's may be more known for healthy fare than burgers/fries/coke. Remember at the end of the day the McDonald's board only cares about making money, not what food items they sell. If they can make a killing selling low-fat, high-protein vegan-ish fare they will.
