Aside from McDonalds obeying the heavy left-wing regulations and then eventually moving to that left-wing vegan/vegetarian menus. Yeah, they do seem to have failed.

There is nothing wrong with protecting local cuisine. There are a lot of things wrong with processed, prepared food. Which is so very fun when you are in your 20s and it starts eating away your health without you even noticing.

Regardless, people do preserve their local traditions. Mediterranean cuisine is still the cuisine in Mediterranean and the corporate profit machines which you defend for some reason, are so unpopular that they are adopting and serving local cuisine.
