Doesn’t a mess come from mafia controlling dumpster companies or something like that? By the way, I love this place called pizzeria da Michele. Best pizza in the world.
The problem that the previous poster is referring to is more that people just don't care a lot about things like dirty streets, pollution, noise, chaos, crowds, etc. They are actually super relaxed about things that would cause people in other places to throw fits. But this also contributes to a kind of decadence.
