Well... i do not know what you are doing in rio de janeiro...i wonder.It's the same no matter where you go in the world!, some people will not or can not achieve a decent life as we call it in civilized society. The government can spend hundreds of billions on these so called poor and under privileged people with little effect. The United States is a great study in this. Decades of Affirmative action, race based quotas for college grants, advancement in all branches of government, small business and yes over 100 billion spent on the chocolate city (New Orleans) and the state (Louisiana) with little advance except to highlight social corruption! All you social scientists are full of it period! Some people are self destructive in nature just like some are gay or like to party.
your statement is ignorant and typical of a decaying elite that lives in Brasil.
Go and read about the countru and its corrupt government before you make such a non sense statement about the dialetics of poverty.
