I am not sure which one would people 'fairly' because there will always be individuals or groups of people treating others differently everywhere, they are conservative, always jealous, selfish, and -not-knowledgeable-
One current big problem I see is that US is like a discrete[/size] math problem. People outside say US is full of "individualism", the people are aggressive, rude too, they hate American people I can see it in their voice and eyes, and even their broadcasted TV programs. No one says it straight but does kind of educate their peoples in a way, politically and spritually speaking, to spit saliva on other people's face.
To explain why I say 'discrete', I can say it is due to selective pressures, I think, from a population that is composed of originally different ethnicities and surely an urge to group them up is completely absurd and out of place. But on the other hand, such a diversity becomes benefitial as it creates an environment for mutual interactions, competition, leading to the development of science and technology which on an average scale i think, US is still a leader.
Some people say humanity is to help people, some say it is to do things fairly and morally, but I always try to remind me that I do have two faces...
