xandman, your chart only tells half the story. By normalizing every year to 100, you missed the most important aspect of the health of MCD - revenue growth:

You see, revenue has been declining and the decline accelerated in the last year. Your chart actually showed the desperation of prior management, instead of trying to arrest the decline in sales, they tighten cost control so much that very likely they hurt the business and revenue growth instead (but masked the problems). We call this a downward spiral. That was probably why the board fired him.
On the positive side, operating margin, return on equity, return on capital are all exemplary but as I said, coupled with declining sales, those are actually a sad story.
I am actually most impressed with their US federal corporate tax rate (of ~36% in 2014), which is the maximum the US government charges companies. They are one of the very few that paid the max rate. Even companies we think of as progressive, like AAPL, MSFT....paid much much less taxes. Folks that criticize MCD, especially the liberals should take note. They may not pay their workers well but they sure paid more than their fair share of tax.
I just want to have a good discussion of business fundamentals and different view points.
Cheers.
