brazil being one of the biggest emerging economies, new technologies, living conditions and social policies are changing at a fast pace to adequately support and compliment the modernization of the country and facilitate the betterment of the lives of its people - the list of social policies is long, and they address issues that are high on the locals consciousness including health care, housing, law enforcement, education, and transportation. 

trying to debate the effectiveness of these policies are topics of discussion very likely to offend a resident - best avoided, these topics should always be approached with extreme care, as a visitor's opinion can easily be misunderstood and qualified as superficial, ill-informed or opinionated, leading to unnecessary negativity.
