Argentina is Argentina, and Brazil is Brazil.
In Argentina, when beef becomes too expensive, you get major riots in the streets, and the government falls. Brazil does not have this problem, because Brazilians eat a lot less beef, the diet is far more varied, and do not riot over high food prices. Argentine restaurants have a dozen beef dishes on the breakfast menu, in a country where most people just have a croissant (media luna) and coffee for breakfast. Beef is the only main dish for dinner. If you want anything different, you go to a vegetarian restaurant,, which have the best veggie food I have ever eaten.
The beef is better, too.
