Can’t think of any way that your post makes any send on any level!
Almost nobody cares about whole grain breads at McDonald’s.
Nor do they want to pay more for it.
McDonald's started out by offering nutritional enough foods at a good price. They lost their way.
The problem is Americans are eating better food. Even in fastfood the quality has generally gone up. And McD is stuck being the “fast and crappy” place. And sure, the people still going to McD are OK with that, but that number is shrinking. All the new guard are making better food, and most of the old guard has reinvented themselves (look at Wendys, a vastly different place than they were just 10 years ago and sales and profits are climbing). McD keeps trying to reinvent themselves but they can’t make it stick, the fast and crappy crowd doesn’t like any of the new changes, and the crowd that actually wants good food doesn’t believe them.
