The culture, the morals, and the politics of the country are different. What you are being shown is the last stages of the death of "The Rule of Law".
Folks do not trust the government, the government has completely failed to provide for the people, and the people have decided that instead of revolting against their government they will create a parallel society and system. Instead of expending energy trying to fix the government most folks in Brazil ignore it and run their own system for providing things that the government cannot/will not provide - like running water, health care, a stable currency, and controlling those who break the rules. Of course the rules that the parallel system enforces very rarely look like the kinds of laws the government usually passes. But people have a roof over their heads and food in their bellies most of the time.
The fortunate thing about the culture/lifestyle/system depicted is that it is localized. The unfortunate thing is that it is spreading and growing because the "citizens" do not consider their established government capable of doing anything about it.
