The Big Mac index is pretty stupid though, since the ingredients in various countries are different and not sourced from the same place. Here en Europe McD tries to be somewhat middle class while I'm the us it's absolute trash.
Other than that price differences in food between $ and CHF are likely mostly explained because work hours simply cost a lot more around here.
Not sure why you would think that. McDonalds is famous for catering it's menu and service to it's locale.
In Australia they were required to serve real chicken in their nuggets, and they're always advertising that they use locally sourced beef for their burgers.
They also rebranded in a sense to upmarket themselves, and started selling salads, cakes and coffees in order to sneak a foot into the Australian cafe scene.
Hence, it’s a non standard product, and a pretty dumb basis for an index.
I saw Americans amazed at Europe’s “real cheese”, and Coca-Cola with “real sugar”. I have never heard the explanation for “real chicken” yet.
This is funny and scary at the same time.

It was Pink Slime for awhile. "Real Chicken" is the continuing strategy to claw back from the PR nightmare.
