I observe that, the far right in the US often viewed the people of the third world as backward, stupid and even barbarian, whose development depends on the help from the West; but the far left think of the people of the third world as innocent, peaceful, and free from all the materialist desires of capitalism. I just think both views are far from reality.
Reality is of course complicated. I have my own simplistic view though, I think the people of the third world are as bad as those in the first world, they are just as prone to prejudice, violence or greed. Yes I'm pretty cynical. So it's amazing that I met quite many nice and noble friends! I doubt my experience can be generalized into an assertion that there are many good people in the world though. I am probably just lucky.
