Pitipur,
You seem to misunderstand that the entire basis for this forum is drawing wide-ranging conclusions based on limited personal experience. eg:
I heard of someone getting mugged in Recoleta = Crimewave!
I saw the dollar blue go up = Economy in shambles!
I saw someone sleeping in the street = Poverty is getting worse!
Please don't confuse matters by bringing in actual statistics or by pointing out how hard it is to judge a city of millions based on personal experience.
