I am in Catalonia at the moment. You see their flags everywhere but imo it is all just populism.
Politicians like selling the idea of independence because it sounds good and it's easier to sell to moderates than blaming the immigrants.
But actually it doesn't solve anything. Catalonia has immense dept and I am not sure they could shoulder independence.
I also oppose the whole idea that somehow everybody is better off by themselves. It's just not true.
