It isn't unfair because a third world country is a third world country on principle; most African nations for example are in such horrid conditions not because of 'fate' or some other mystical reason, but because few (if any?) countries in Africa have ever had protected individual rights, specifically property rights.
OK, you're treading on thin ice here mate... and once again displaying your US-centred ignorance. The real reason Africa is the mess it is today is because it was exploited for over a century by European colonialist powers, who left a legacy of poverty, dependence and in-fighting. I'm not saying that is the root of all
the problems we are seeing, but it sure accounts for much of the status quo.
Did you know, before the Europeans arrived in Africa there were already advanced civilizations there, such as the Benin, Zulu, and of course Ethiopia.
