Questions About "Gomorrah" (Matteo Garrone)

I just saw the DVD-its a very complex movie, but though provoking. The film shows the devastating effect of organized crime (the Neopolitan Camorra).
Anyway, the public housing project where most of the kids lived-it looked like a version of hell-are they really that bad?
And the Chinese garment factory-do these places really exist in Italy?
The toxic waste racket looked evildo they really have a pile of it higher than Mt. Everest?
In any event, was any reform undertaken after the movie came out?
