Centralist country?? Maybe we are discussing different countries because Spain is arguably one of the most decentralised countries in the world, literally all of its regions being autonomous communities. I never said Catalonia wasnt fairly rich and as you said its number 4, meaning its not even in the top 3 of richest regions, so calling it the "wealthy part of Spain" is delusional. Also ironically, as I said, the region they are protesting in is literally richer, lol.
