In Switzerland where you can tell on every piece of supermarket meat what kind of farming/standard it is trough a easy to follow colour code and some kinda Trustable labels, you very well see customer pick the more expensive ones.

Same thing in Austria, clear labelling, good availability, people are buying it.

Nobody in Spain does because none of their supermarkets has any concept for labelling the meat standard

So it's easy to say nobody would if they didn't really try
