From what I understand the reason why Spain has to rely on tourism now is because we got rid of a lot of our secondary and primary sector during the 70s just during the crisis
Most Spaniards wish that wasn't the case. People are getting tired of living in a country that's been turned by greedy politicians into a chiringuito for the English and Germans to party in.
Im biased but I don't agree with calling Spaniards entitled. It's not the tourists the crux of the issue but rather the consequences of mass tourism and relying on such phenomena for carrying the economy. I think most people would agree with that, no matter how cranky they might be towards tourists
