I recommend the 2011 documentary Italy: Love It or Leave It. It's about two guys who drive through Italy in an old Fiat 500 to decide if they should stay or move away. In the process they talk about modern Italy.
I guess in a way it doesn't take much to make a city look clean (or dirty) but it takes a lot of work for it to be constantly good looking.
While Spain is certainly not on Switzerland or Japan’s level of cleanliness, I think it is miles away from Italy. Just the taxi ride from Fiumicino to Rome made me feel like I was in Brazil again - crooked, dirty road signs, wild vegetation growing everywhere, fading markings/lines, and a general state of chaos on every road.
Combined with the economic outlook, this doesn't bode well for the future.

You may not like Saviano but a lot of what he has written and predicted in his book has been validated. The fact that he unmasked Camorra at grave risks to his own life makes it hard for me to see him as "gaining" or exploitative. He lives his life in hotel rooms or police barracks under constant guard [1].
