Coming from South America there's this concept call 'viveza.' It means taking advantage of others whenever you can. That's why most South America-in Peru at least- people are so distrustful of strangers-unless they are white foreigners- since strangers could screw them over. To protect themselves people in third world countries tend to be very cliquish and adopt a sheep mentality.
