Wow. Just....Wow. The very idea that these ridiculous concerts cause the leaders of the world's businesses to do anything other that snicker into their sleeves is utterly idiotic. Good God. You better face up to the fact that there WILL ALWAYS BE POVERTY! Basic human nature is greed and desire for power - that very nature REQUIRES that people be kept down for others to rule/profit. I'm not saying it's right, but I'm saying that all people suffer from these faults - some control them better is all.
Man, this is nothing more than a meaningless bleeding-heart circle-jerk. It's designed to make people "feel" better. It does absolutely nothing.
Want to make a real difference? Quit your job and go to Africa and help them. That's the only sure way to make any sort of difference.
Wait, what's that? You CAN'T quit your job? Don't really care, do you? Anything less is just a bullshit exercise in making you feel like a real hero.
Just remember - any aid money that goes to Africa has to go through the already corrupt governments that are the root of the problem. G8 and Live 8 isn't going to solve shit, no matter what they decide.
