It's true that some charities don't use the money effectively and that the governments of such nations often use Aid money to buy arms.
But donations and aid DOES help somewhat. Doctors without Borders do great work and they need donations to ensure they can treat enough people. Oxfam gave mosquito blankets and peanut-butter based nutritional supplements which HAVE saved lives of people in Africa.
Yes, not all the aid makes a difference. Yes, some charities take 90% of the money donated for "administration purposes" and give only 10% to the people (and only 5% of that actually makes it through after all the bribes and such). Yes, aid will not, and cannot fix Africa's problems (which aren't entirely the fault of the whites you know - some of Africa's problems ARE definitely caused by white people, but there's a lot caused by their own governments and inter-tribal hatred). But please do donate - I'm not asking you to give your life-savings to them. But if you donate 5, 10, 15 dollars to the UN or Oxfam or to Doctors Without Borders, some of that money will go to helping people, I can guarantee you that - and the more people donate, the more makes it through. A mosquito net can save a life - it can. Just a little bit more food can mean the difference between life and death for many of the sick and the dying.
No, foreign aid will not, and never could, transform Africa or any nation for that matter, into a paradise. But it can allow one child to not go hungry for a day. It can save the life of a father or a mother so that they can look after their child. Hell, 50 bucks can help pay for part of a water pump and filtering device for a village - this could literally save tens of lives and prevent up to 100 people from getting sick from water.
I do feel bad for the sick and the dying in Africa - you'd have to be virtually inhuman (or a racist) to not feel bad for them. I won't pretend that I bawl my eyes out whenever I see dying or sick children on my TV screen - I'm far too removed from the situation to have a strong emotional response, but I at least have SOME emotional response to seeing these images.
And I do donate - not as much as I probably should, but I do donate. It does not really give me a warm-fuzzy feeling, as I know that the good that is possible is very limited. But at least it's some good, and at least the gnawing guilty voices in my head don't shout so much after I do donate.
