Are you surprised that people in cities with less money are friendlier?
I haven't been to countries where people mostly are poor, so I can tell about my experience in usuall countries with mixtured societies. I think that people with less money are more open to others. They don't think about themselves in the same way as rich people do. I think that people in cities with less money find the sense of life in non-material things. They love speaking and communicating, they love being in public. People with money sometimes can feel themselves really comfortable being alone. Of course rich people more pragmatic, stronger and maybe they can think that other people have to respect their succes. But I definetely can say that there are good people in low society and in high, and the same about bad people.
